Vaginal sex typically lasts three to seven minutes, according to a Society for Sex Therapy and Research member survey. So how long should vaginal sex actually last? Many people consider the end of sex to be once all involved parties have climaxed. This may be achieved through touching, oral sex , vaginal sex, anal sex — or a combination. If intercourse is the only component in your definition of sex, then sex will likely only last a few minutes. Researchers in one study found that the shape of the penis — specifically the ridge around the head — may have evolved to be more competitive. The ridge is able to displace any preexisting semen in the vagina. Deeper and more vigorous thrusting results in more semen displacement. This allows the ejaculating partner to make room for their own semen, increasing their chance of reproduction. Using competitive evolution as a backdrop, this could explain why some people find it painful to keep thrusting after ejaculation.
Why do we have sex for so long?
If you've ever wondered how the duration of your hookups compares to how long other people are spending in bed, sex toy company Lovehoney has some stats for you. Its recent survey of 4, of its customers found that opposite-sex couples had sex that lasted 19 minutes on average, with 10 of those minutes spent on "foreplay" and nine on penetrative intercourse. While 52 percent of respondents said they were satisfied with this number of minutes, 19 percent of women and 23 percent of men said they wished their sex lasted longer. What they wanted to last longer — the foreplay, the intercourse, or both — wasn't addressed, but it's an important distinction. Where did the idea "the longer a penis is in a vagina, the better" come from?
You came here looking for an answer, and an answer I will give you: Sex should last one hour, 34 minutes, and 22 seconds—the exact runtime of Wayne's World. Shyeah, right! Marathon sex sessions are used as a measurement of just how steamy an evening was. And while quickies can be fun, they should constitute a piece of a balanced sex life—not the whole thing. While there's no magic number, one study back in in the Journal of Sexual Medicine asked a bunch of sex therapists for their opinions on how long sex should last. Their guidelines separated sex into four categories: adequate, too short, too long, and desirable. Good for them!
