Measured from penetration to ejaculation in most stopwatch-based studies, the typical intravaginal ejaculation latency time (IELT) centers around roughly 5 to 6 minutes, with a frequently cited mean o...
Clinical consensus and mainstream medical reviews say prostate massage is unlikely to reliably treat erectile dysfunction (ED) and carries risks; some older studies, small trials and many anecdotal re...
Research shows a complex, non-deterministic relationship between penis size and female orgasm: some studies report associations between women’s preference for longer or thicker penises and , while oth...
Available reporting shows no single, rigorous, widely cited survey that definitively answers “what percentage of women find men in thongs sexually attractive”; most sources are small polls, brand/blog...
Multiple studies and polls measure women’s interest in dominance/submission as a sexual preference or fantasy — many report large shares who fantasize about being dominated or who enjoy consensual “ro...
High‑quality, peer‑reviewed work finds a measurable connection between women's preference for deeper/longer penile–vaginal stimulation and a higher frequency of vaginal (but not clitoral) orgasms, an ...
Three decades of modest, mostly survey-based research find a reproducible correlation: women who report preferring deeper penile–vaginal stimulation or a longer-than-average penis also report more fre...
Scientific studies show mixed evidence linking penis size (length and girth) to women’s sexual pleasure: some surveys and preference studies find modest preferences for larger girth or length in certa...
Peer‑reviewed studies show a , but direct, quantitative evidence specifically linking measured penis girth (circumference) to female orgasm frequency is limited. The strongest empirical results derive...
Only one randomized trial specifically testing as a therapeutic adjunct for postpartum pelvic floor recovery has been published: a prospective randomized two‑arm study that compared daily Kegel exerci...
Large clinical reviews find that stretched (manually extended) flaccid length tracks erect length better than relaxed flaccid length: pooled means across studies are about 9–9.2 cm flaccid, ~12.8–13.2...
Existing academic surveys report an association between women who prefer deeper penetration (i.e., longer penises) and higher frequency of vaginal orgasm in some samples; one influential online-survey...
A small set of traction and implant products are commonly marketed for penile stretching or aesthetic enhancement, and several vendors explicitly claim FDA clearance or approval—most notably SizeGenet...
There are no medical organisations that set a recommended "frequency" of sexual activity by age; guidance instead focuses on consent, safety, prevention, and age-appropriate education (WHO on adolesce...
Studies do not identify a single “girth threshold” at which sexual satisfaction uniformly increases or discomfort begins; research instead reports associations between larger perceived girth and great...
Available reporting shows multiple health and practical issues can arise when penile girth is far above average: extra girth can increase friction-related injury and infection risk and in extreme case...
Research finds mixed but consistent signals: several studies and surveys link greater penis girth (and sometimes length) with increased reported pleasure for some women, especially for vaginal orgasm ...
No randomized head‑to‑head trials comparing the penile traction device directly against other specific penile traction devices were identified in the provided reporting; published randomized studies o...
Peer‑reviewed work on women’s sexual practices and ejaculation preferences shows a mixed landscape: population‑level probability surveys document diverse preferences for stimulation and a strong role ...
Medical studies report a modest, specific correlation: women who report preferring longer-than-average penises also report higher frequency of vaginal orgasms during penile–vaginal intercourse, but sh...
