Key Takeaways
Traction devices grow your penis — pills and surgery don't
“In 8 months I had increased my penis length by 3.1cm (1.22 inches) and my penis girth by 0.81cm (0.31 inches).”
No pill has ever worked. If one did, big pharma would mass-produce it. Penis enlargement surgery only cuts tendons for a bigger flaccid hang — zero erect-size gain. But mechanical traction does work, using the same principle as neck rings worn by the Kayan Lahwi tribe of Myanmar: sustained tension causes micro-tears in tissue that heal longer and thicker.
The author started at 5.39 inches and used four tools over 8 consistent months: the All Day Stretcher (a traction device worn 4-8 hours daily — clinical trials show ~1 inch gain in 6 months), jelqing (an ancient massage technique forcing blood through the shaft), manual ligament stretching, and the Zen Hanger (hanging weights for 30-60 minutes daily). The principle mirrors muscle growth: progressive overload, consistency, recovery.
Strong erections depend on five factors you can all optimize
“…you could have a jet engine under the hood but it doesn't matter unless your car has wheels.”
Five pillars of erection quality:
1. Cardiovascular health (penile plaque buildup is essentially a "heart attack of the penis")
2. Nitric oxide production (relaxes blood vessels so blood floods the chambers)
3. PC muscle strength (keeps blood trapped during erection)
4. Healthy testosterone levels (drives libido)
5. Mental state (presence, calm, arousal)
The first four are the engine; your mind is the wheels. Actionable supplement stack: pomegranate juice daily (reverses arterial plaque AND protects nitric oxide), Vitamin D 2000IU, L-Arginine 3g, Yohimbine 5mg, Pycnogenol 120mg, and Stinging Nettle Root 1000mg. Eliminate alcohol, sugar, and cigarettes — each independently constricts blood vessels and sabotages testosterone production.
Kegels are the Swiss Army knife of male sexual performance
“If there is one exercise I would recommend above any other for men's sexual health it's the Kegel.”
Kegels strengthen the pelvic floor — the PC and BC muscles controlling erection hardness, ejaculation force, and orgasm intensity. Studies show regular kegels help men with erectile dysfunction regain normal function. A strong enough kegel can physically stop ejaculation mid-orgasm, letting you continue having sex.
The progressive regime spans weeks: start with 100 rapid contractions daily, advance through 5-second holds, 10-second holds, then erect kegels (performed with a full erection), weighted hold kegels (towel draped over the erect penis for resistance), and finally reverse kegels (pushing outward to train the opposing muscle). Isolate the pelvic floor — don't tense buttocks, legs, or abs. Skip them right before sex since the muscle will be fatigued.
A 30-day dopamine fast makes a naked thought electric again
“…something as simple as the thought of a naked woman will have a far stronger effect on our arousal than it did previously.”
Porn and social media bombard dopamine receptors until the brain defensively shuts some down, creating a vicious cycle: you need ever-more-extreme stimulation to feel the same arousal. This dulls both mental desire and physical penis sensitivity. The fix: eliminate sugar, alcohol, drugs, gambling, porn, masturbation, and social media for 30 days to let disabled receptors repair themselves.
After the fast, use progressive sensitization to rebuild arousal without relapse: masturbate to one video only (no switching), then downgrade to photos for two weeks, then erotic stories, then pure imagination. By the end, your brain generates its own arousal internally — no screen required. A welcome side effect: surging sex drive and motivation to pursue real connections.
Master edging and you unlock lasting power and multiple orgasms
“…when you masturbate if you jerk off for 2mins and bust your nut right away you are effectively training your body to behave that way during sex.”
Edging means approaching orgasm, then stopping. It's the book's single most versatile technique, serving four purposes: lasting longer in bed (trains ejaculatory control), bigger cumshots (builds up seminal fluid), heightened sensitivity (keeps the penis primed), and multiple orgasms via "ruined orgasms" — tipping just past the point of no return, then ceasing all stimulation so you ejaculate without the full prolactin surge, preserving your erection for another round.
The author edges the night before and morning of every scene. Supporting techniques for lasting longer: breath control (longer exhales calm the nervous system), counting objects in the room to engage the logical mind, and the "kink the hose" method — bending the penis base forward to cut sensation to the frenulum.
Eat cholesterol at night — testosterone peaks before 8am
“Testosterone is made from cholesterol, it's literally the precursor molecule for its synthesis.”
Cholesterol is the raw building block your body uses to manufacture testosterone, and peak production occurs before 8am on a normal sleep cycle. Consuming cholesterol-rich foods in the evening gives your body the fuel for overnight synthesis. The author's pre-scene ritual: a shake of 4 raw eggs with vanilla protein powder — "you'll wake up with a raging boner like you're 16 again."
Best sources: pasture-raised eggs with golden yolks, grass-fed beef and butter, lamb (always grass-fed), wild-caught fish. Pair dietary optimization with competition: Spanish researchers found 4 weeks of strength training boosted resting testosterone 40% and dropped resting cortisol 24%. Over half the male porn stars the author knows do boxing or Brazilian Jiu Jitsu.
The pornstar mindset: presence, calm, and arousal in a loop
“When you are truly present in the moment you are immune to the thoughts that would otherwise kill your erection.”
Every successful male performer has flopped on set early in his career. The three mental elements that separate survivors from washouts form a positive feedback loop: being present in the moment (not anxious about outcomes), eliminating the fight-or-flight response (which redirects blood from the penis to the limbs for survival), and being sexually aroused (finding something attractive about any partner, even if she's not your type).
As arousal increases, presence deepens. As presence deepens, fight-or-flight fades. Tools to enter this state: smelling the back of her neck for pheromones, daily meditation (even 5-10 minutes), dirty talk as self-arousal rather than partner-pleasing, and body language anchoring — training a physical gesture to trigger horniness, like Pavlov's bell for boners.
Break performance anxiety with your body, not your brain
“Motion creates emotion, so if you want to change your mind you have to change your body- you cannot think your way out of anxiety.”
Mind and body run a two-way loop. Anxiety produces hunched posture, downcast eyes, folded arms — and those postures reinforce the anxiety. The escape is physical, not cognitive: jump up, beat your chest, walk like a champion. The absurdity breaks the spiral and triggers confidence.
Specific protocols: the 4-7-8 breathing technique (inhale 4 counts, hold 7, exhale 8 — the extended exhale activates the parasympathetic nervous system), progressive muscle relaxation (tense then suddenly release each muscle group from feet to shoulders), cold showers before performing (forces present-moment awareness and boosts testosterone), and pre-scene routines modeled on basketball free-throw rituals — repeating the same sequence anchors calm regardless of pressure.
Focus on the 1-2pm clitoral position and teach her four words
“…if a woman tells you she's going to cum then you keep doing exactly what you are doing at the exact same pace and intensity until she cums, don't change a god damn thing.”
Tease the orgasm out slowly. Begin with thigh kisses, warm breath through panties, licking labia — ignore the clitoris until she's desperate. When you finally reach it, use barely-there pressure (light enough to feel through paper). The scientifically studied sweet spot: the 1-2pm position on the clitoris (imagining 12 o'clock at top center).
Replace vague "does that feel good?" questions with four directional words: Harder, Softer, Faster, Slower. This removes ego pressure from her honest feedback. Add G-spot finger stimulation in a "come hither" motion, matching finger speed to tongue speed. Patience is everything — the author has spent 45 minutes giving a woman her first cunnilingus orgasm. Never rush.
Cut high-glycemic foods, not calories, for abs and erections
“…with a few changes to your diet and exercise you can start to heal and see your body bounce back to normal within 6-12 months.”
High blood sugar triggers insulin, which shuttles excess glucose into fat cells. Its counterpart, glucagon, burns stored fat — but only when insulin is low. So eat low-glycemic foods and eliminate bread, pasta, rice, sugar, and alcohol. No calorie counting needed; eat unlimited meat, vegetables, and healthy fats.
This paleo-style approach (the author's 45-day body transformation proved it) simultaneously improves erection quality by reducing inflammation and insulin resistance — which tanks libido and chronically elevates cortisol. Sugar is especially destructive: it creates leptin resistance (killing sex drive), spikes insulin (storing belly fat), and triggers dopamine responses similar to cocaine, making it fiercely addictive. The body's capacity for recovery is enormous if you give it the right inputs.
Analysis
Cooper's book is, at its core, the systematic application of sports science principles — progressive overload, periodization, nutrition timing, mental performance training — to male sexual function. This framework is its genuine and underappreciated contribution. Where most sexual health resources offer vague lifestyle platitudes, Cooper provides specific rep schemes, supplement dosages, and progressive training protocols with the precision of a strength coach programming an athlete's cycle.
The most intellectually substantive section is not the enlargement material but the mental performance chapter, which independently reinvents concepts from established disciplines: pre-performance routines as anxiety anchors (sports psychology), present-moment awareness as anxiety dissolution (mindfulness-based stress reduction), and body language anchoring (neuro-linguistic programming). The three-element mindset framework — presence, parasympathetic activation, and arousal — maps closely onto what performance psychologists call optimal arousal theory.
The dopamine fasting and progressive sensitization protocol represents the book's most broadly transferable insight, reflecting legitimate neuroscience around hedonic adaptation and receptor downregulation. In an attention economy optimized for novelty escalation, the principle of deliberately reducing stimulus intensity to restore baseline sensitivity has implications extending well beyond sexual performance into productivity, satisfaction, and mental health.
Critically, the evidence quality varies substantially across topics. Penile traction devices have modest clinical trial support, but published effect sizes are smaller than the author's personal results suggest, and his experience may not be representative. Some supplement recommendations — particularly cabergoline, a dopamine agonist with serious neuropsychiatric risks — receive insufficient cautionary weight. The dietary advice is largely consistent with current nutritional science favoring whole foods over processed carbohydrates, though the anti-legume stance contradicts Blue Zone longevity data. Readers should treat this as a practitioner's field guide — valuable for its systematized protocols and experiential pattern recognition — while consulting medical professionals before implementing the more aggressive interventions.

Glossary
All Day Stretcher (ADS)
penis traction device worn dailyA mechanical traction device inserted over the penis and locked at adjustable tension, designed to be worn 4-8 hours daily under clothing. It creates sustained micro-tears in penile tissue that heal longer over time. Clinical trials show approximately 1 inch of length gain over 6 months of consistent use. Can also help correct penile curvature by orienting tension to the opposite side.
Jelqing
ancient penis massage exerciseAn exercise originating from the ancient Middle East involving gripping the lubricated penis in an inverted OK sign and slowly sliding from base toward the glans, forcing blood through the shaft to create micro-tears. Performed at 20-50% erection for length gains or 60-100% erection for girth gains. Uses a progressive rep scheme starting at 25 reps per day, building to 2 sets of 500.
Progressive Sensitization
downgrading masturbation stimulus graduallyA post-dopamine-fast technique for restoring sexual sensitivity by systematically reducing the intensity of masturbation material over several weeks: from one video only (no switching), to photos for two weeks, to erotic stories, to pure imagination. Trains the brain to generate arousal internally rather than depending on escalating external visual stimuli.
Ruined Orgasm
ejaculation without full mental releaseA technique for achieving multiple orgasms where the man tips just past the point of no return and immediately ceases all physical stimulation. This triggers the physical ejaculatory response without the full prolactin surge in the brain that normally causes the refractory period. The erection is maintained and another orgasm can follow. Requires extensive edging practice to master.
Point of No Return
threshold where orgasm becomes inevitableThe precise moment during sexual stimulation beyond which ejaculation can no longer be voluntarily stopped. Developing intimate awareness of this threshold through masturbation practice is considered the foundation of orgasm control. Central to edging, lasting longer techniques, and achieving ruined orgasms.
The 3 Elements of a Pornstar Mindset
presence, calm, and arousal frameworkThe author's mental performance framework for sexual function under pressure. Element 1: Being present in the moment, eliminating anxiety about past failures or future outcomes. Element 2: Eliminating the fight-or-flight response, which redirects blood away from the penis toward the limbs. Element 3: Being sexually aroused by actively finding something attractive about any partner. The three form a self-reinforcing positive feedback loop.
Body Language Anchoring
Pavlovian physical trigger for arousalAn NLP-derived technique where a specific physical gesture or motion is repeatedly paired with a desired emotional state until the gesture alone triggers the state. Example from the book: porn star Mick Blue conditioned himself to orgasm on command by consistently rubbing his belly before climax, creating an automatic association. Can also be used to trigger relaxation or arousal before performance.
4-7-8 Breathing Technique
anxiety-reducing structured breathing patternA breathing exercise for reducing fight-or-flight response: inhale slowly through the nose for 4 counts filling lower then upper lungs, hold for 7 counts, exhale through pursed lips for 8 counts while relaxing face, jaw, shoulders, and stomach. The extended exhalation activates the parasympathetic nervous system, slowing heart rate, lowering blood pressure, and relaxing muscles.
Kink the Hose
bending penis to delay orgasmA technique for delaying orgasm where the man grabs his penis at the base and bends it forward against its natural upward curve, creating a kink in the urethra that cuts off pleasurable sensation to the frenulum—the most sensitive spot near the glans. Can be repeated multiple times in the same session to prevent reaching the point of no return.
