Do delay sprays work?

Topical lidocaine-prilocaine has good trial evidence for extending latency. Over-application can cause numbness for both partners.

Is premature ejaculation psychological?

Lifelong forms have a substantial neurobiological basis. Acquired forms are more often anxiety- or erection-related. Both are treatable.

Do stamina supplements help?

Very little direct evidence. Cardiovascular fitness, pelvic floor training and behavioural technique outperform anything in a capsule.

Sexual Health

Moderate Evidence

Sexual Stamina

Enhanced endurance and performance during intimate activities.

TL;DR

Stamina in bed is mostly cardiovascular fitness, anxiety management and technique. Premature ejaculation is a common, highly treatable condition — behavioural therapy and prescription options beat supplements.

Why It Matters

Sexual stamina spans cardiovascular capacity, ejaculatory control and psychological arousal regulation. Lifelong premature ejaculation has a strong neurobiological component involving serotonergic signalling and responds to SSRIs and topical anaesthetics; acquired forms are more often linked to anxiety, erectile difficulty or prostatitis. Persistent erectile difficulty is a recognised early marker of endothelial disease and should trigger cardiovascular assessment. Pelvic floor training has genuine randomised trial support and is underused.

How to Measure

Biomarkers

Intravaginal ejaculatory latency time

IIEF or PEDT scores

Blood pressure and lipid panel

HbA1c

Cardiorespiratory fitness (VO2max or step test)

Testosterone where indicated

Optimization Protocol

1) Build aerobic fitness — the strongest general lever, improving both endurance and endothelial function. 2) Train the pelvic floor; randomised trials show meaningful improvement in ejaculatory control from a 12-week programme. 3) Use behavioural techniques such as stop-start and squeeze, which have decades of clinical use and reasonable evidence. 4) Reduce performance anxiety through paced breathing, sensate focus exercises and, where needed, psychosexual therapy. 5) Limit alcohol, which impairs both arousal and control. 6) Treat any underlying erectile difficulty first — rushing to ejaculate is often compensation for losing an erection. 7) Discuss prescription options with a clinician: topical lidocaine-prilocaine and on-demand or daily SSRIs are effective and well studied. 8) Treat supplements as marginal here.
