Four Pillars of Sexual Health
A foundational framework for optimal sexual function comprising Fuel (nutrition), Strength (cardiovascular, resistance, pelvic floor), Environment (stress, sleep, chemicals, social circle), and Confidence (knowledge, communication, novelty).
Sensate Focus
A therapeutic technique to reduce performance pressure during sex by focusing on non-genital touch and exploring each other's bodies for pleasure, gradually reintroducing genital touch and penetration.
Canary in a Coal Mine
A metaphor used to describe erectile dysfunction, indicating that it often serves as an early warning sign for underlying cardiovascular issues that may manifest as heart disease or strokes within 3-5 years.
Homologue
Refers to anatomical structures in different sexes that develop from the same embryonic tissue, such as the clitoris and penis, or the male prostate and female Skene's glands.
Post-Coital Dysphoria
A phenomenon where individuals experience feelings of sadness, anxiety, or depression after sexual activity, attributed to dramatic neurochemical shifts in the brain following orgasm.
C Tactile Afferents
Specialized nerve fibers in the skin that respond specifically to slow, gentle human touch (around 3 cm/second), contributing to feelings of pleasure and enjoyment, and are not activated by non-human touch.
Aromatase
An enzyme found in fat tissue that converts testosterone into estrogen, explaining why increased body fat can lead to lower testosterone levels and potentially higher estrogen levels in men.
Free Testosterone
The small percentage (1-2%) of testosterone in the body that is not bound to proteins and is therefore readily available for cells to use, making it a key indicator of symptomatic low testosterone.
Sexual Flow State
A state of deep immersion and enjoyment during sexual activity, achieved when there is a slight challenge or novelty, making the experience feel effortless and highly pleasurable, similar to a flow state in other activities.

Sex is highly important for overall health, with studies showing people who have sex once a week live 49% longer than those who have it once a year, and it serves as a cardiovascular workout and a vital form of human connection.
Younger generations are having less sex due to increased distractions from technology, a shift towards superficial dating app connections, a lack of education on healthy sexual communication, and exposure to unrealistic portrayals of sex in media.
Erectile dysfunction is defined as the inability to maintain an erection sufficient for intercourse, meaning an erection may occur but dissipates before ejaculation or climax.
Pornography can impact your sex life if you become habituated to specific, often unrealistic, forms of stimulation that your partner cannot replicate, or if you feel guilt or shame about your consumption, which can lead to performance anxiety.
Morning erections are a healthy sign, indicating good blood flow to the genitals, balanced hormones (especially high morning testosterone), and proper nerve function, with healthy men typically experiencing 3-5 nocturnal erections per night.
The "use it or lose it" principle suggests that if the penis or clitoris does not receive regular blood flow through nocturnal tumescence or sexual activity, the tissues can develop fibrosis (scarring) and potentially shrink over time.
Chronic stress elevates cortisol, which dampens testosterone and keeps the body in a sympathetic "fight or flight" state, making it difficult for the nervous system to relax into the parasympathetic "rest and digest" state necessary for arousal and sexual function.
Pelvic floor muscles contract rhythmically during orgasm and ejaculation, contribute to blood flow to the genitals, and are crucial for urinary and bowel control; tension or weakness in these muscles can lead to pain, erectile dysfunction, or difficulty orgasming.
Surgical penis lengthening is not recommended due to high complication rates. However, using a penile traction device for 30 minutes twice a day for 3-6 months has shown improvements in length by about two centimeters, though permanence is unknown.
TRT is prescribed to bring low testosterone levels back to a normal range for health benefits, while anabolic steroids are often self-administered at super-physiologic doses to build muscle, carrying severe risks like heart failure and cardiac death.
Yes, TRT absolutely impacts fertility, with about 70% of men becoming infertile after 18 months of treatment, as the body stops producing its own testosterone and sperm.
While GLP-1s offer metabolic benefits and weight loss that can indirectly improve sexual function, they work on the brain's reward pathways and may theoretically decrease desire for sex, similar to how they reduce cravings for food or other addictive behaviors.
To communicate effectively, choose a calm, non-bedroom setting, start with positive affirmations, express curiosity about your partner's feelings, and understand that men often view sex as intimacy while women may see it as added stress.
18 Actionable Insights
1. Prioritize Sex for Longevity
Engage in sex at least once a week, as data suggests people who do so live 49% longer than those who have sex once a year, and every 100 orgasms can increase male life expectancy by 13%.
2. Make Time for Intimacy
Intentionally create space for intimacy and arousal, as modern distractions and stress can hijack your mind, making it difficult to be present and enjoy sex.
3. Address Performance Anxiety
If struggling with performance anxiety, remove the pressure of penetration by focusing on sensate focus—exploring each other’s bodies and other erogenous zones without the goal of an erection or orgasm, then gradually reintroduce penetration.
4. Adopt a Mediterranean Diet
Nourish your body with a Mediterranean diet rich in healthy fats, leafy greens, nuts, lean proteins, and colorful fruits, which can significantly reduce the risk of erectile dysfunction.
5. Meet Fiber Intake Targets
Consume 38 grams of fiber daily for men and 25 grams for women to improve gut health, protect blood vessels, and enhance metabolic health, thereby reducing the risk of sexual dysfunction.
6. Engage in Cardiovascular Exercise
Aim for 150 minutes of moderate-intensity cardiovascular exercise per week, which can improve erectile function as much as medication like Viagra by enhancing blood flow to the genitals.
7. Incorporate Resistance Training
Regularly perform heavy resistance training targeting large muscle groups to improve testosterone levels, maintain muscle mass, and significantly reduce the risk of erectile dysfunction and other sexual dysfunctions.
8. Practice Pelvic Floor Relaxation
If experiencing pelvic pain, urgency, or sexual dysfunction, focus on relaxing pelvic floor muscles through diaphragmatic breathing, figure four stretches, happy baby pose, or child’s pose, rather than just Kegels, which can worsen tightness.
9. Manage Chronic Stress
Actively alleviate chronic stress, as high cortisol levels dampen testosterone and keep your nervous system in a sympathetic state, making arousal and sexual function difficult.
10. Optimize Sleep Duration
Aim for 8 hours of sleep per night, as sleeping only 5 hours can drop testosterone by 15% in a week, equivalent to 10 years of aging.
11. Reduce Endocrine Disruptor Exposure
Minimize exposure to endocrine-disrupting chemicals (EDCs) from plastics and nonstick cookware by avoiding warm plastic bottles, not heating food in plastic, storing food in glass/metal, and choosing cotton fabrics.
12. Curate Your Social Circle
Surround yourself with people who prioritize and speak positively about their sexual and relationship health, as peer attitudes can significantly influence your own approach to intimacy and sex.
13. Diversify Solo Sex Practices
If you find yourself habituated to specific types of stimulation from pornography or masturbation that cannot be replicated by a partner, diversify your solo sex practices or take breaks to help your body respond to different stimuli.
14. Communicate Openly About Sex
Discuss sexual needs and desires with your partner in a calm, relaxed environment (not the bedroom), starting with positives and being curious about their feelings, to foster intimacy and address issues constructively.
15. Introduce Novelty in Sex
Add slight challenges or new elements to your sex life, such as trying a different room, position, or sex toy, to maintain excitement and achieve a “sexual flow state.”
16. Stimulate Erogenous Zones Gently
When exploring erogenous zones beyond the genitals, use slow, gentle caresses (around 3 cm/second), as C tactile afferent fibers in the skin respond best to human touch at this pace.
17. Get Testosterone Levels Checked
If experiencing symptoms like fatigue, brain fog, low desire, or erectile dysfunction, get your total testosterone, free testosterone, and SHBG levels checked to rule out underlying issues.
18. Monitor Ozempic’s Impact on Desire
If taking GLP-1 medications like Ozempic, be aware that they can decrease sexual desire due to their effect on reward pathways; discuss with your doctor if you notice changes in libido.

2 Protocols
Breaking Performance Anxiety Cycle
Dr. Reena Malik- Take the pressure off penetration; explore each other's bodies focusing on sensate focus and other erogenous zones.
- Once comfortable and erections occur naturally, introduce touching genitals but still hold off on penetration.
- After consistently achieving arousal without stress, reintroduce penetrative sex.
Penile Lengthening with Traction Device
Dr. Reena Malik- Place the penis into the traction device, clamping it down.
- Slightly advance the length to create a gentle, non-uncomfortable tension.
- Wear the device for 30 minutes, twice a day.
- Continue this protocol for 3 to 6 months.
