That’s the title of a report over at Science Daily. A survey of 34 sex therapists found: “The average therapists’ responses defined the ranges of intercourse activity times: ‘adequate,’ from 3-7 minutes; ‘desirable,’ from 7-13 minutes; ‘too short’ from 1-2 minutes; and ‘too long’ from 10-30 minutes.” The researchers Eric Corty and Jenay Guardiani conclude, “Unfortunately, today’s popular culture has reinforced stereotypes about sexual activity. Many men and women seem to believe the fantasy model of large penises, rock-hard erections and all-night-long intercourse.”
For a much funnier take on the same phenomenon, here’s a YouTube music video, “Ooh Girl” – An Honest R & B Song. You can also check out our comprehensive sex round up, including the very funny Business Time video, and Greg’s in-depth post, What do those enigmatic women want?
Neuroanthropology 
well it just goes to show what we saw elsewhere today, that the sample process for such studies may be very suspect.
I’m in my advancing years now, but let me tell ya, honest to God, no tall tales exaggeration, I’ve been tangled in the tango all … night … long many a time, and sure, not every night by a long shot, but oh man oh man mark my work lads, those are the nights you’ll carry with you to your grave! mmm— mmm — good.
I don’t think you need a therapist to realize minutes is far better than hours =P even 59 minutes would be way too long! realistically people have to get up for work and for uni. I’m only 21 but sometimes I feel pressure from media articles that talk about ‘hour long’, repeated sessions, tantric sex, and doing it three times a night & sometimes it makes me feel inadequate to not be ‘normal’ .. so this is a good post =p
