Hello everyone and welcome to DNews, I’m Dr. Crystal Dilworth here to discuss Intravaginal Ejactulatory Latency Time; otherwise known as the time it takes a heterosexual couples to have sex. So how long “should” you be having sex for ? And are you…“normal”? Well in attempting to answer these questions, I discovered that “normal” has actually changed with societal expectations and the average length of intercourse has varied over time. So it’s not just biology that we are dealing with here, how long we ''think'' we should be having sex is an influence too. In the late 1940s at the time of the famous Kinsey Report, 75% of males surveyed reported intercourse lasting approximately 2 minutes. A number that seems objectionably short to me personally and could warrant a premature ejaculation diagnosis in these modern times. For the record, the diagnosis of PE is heavily weighted towards self and partner reported satisfaction, but one to two minutes is commonly considered to be premature. Researchers are finding that since the late 60’s, the start of the feminist movement and sexual revolution, intercourse has been taking us slightly longer. How long? Well, survey data from studies done at the University of New Brunswick show that duration of vaginal intercourse is now reported to fall within a range of 5 to 10 minutes, with durations in excess of 20 minutes being undesirable to most study participants. So that average sweet spot is really, as one scientist put it: “approximately the duration of one Marvin Gaye song.” Sadly, sex research is notoriously penis-centric and historically hetero-centric, so these averages only apply to the time it takes for male ejaculation with a female partner and only the more recent studies investigate qualitative measures like sexual satisfaction. In a 2004 study, participants were asked to report how long they wanted sex to last as well as the actual duration of their intercourse. Female study participants indicated that they desired an average of 7 minutes longer then what was standard with their current partners, and men reported wanting another 11 minutes. The funny thing about this survey, is that when asked about duration of foreplay, both men and women also reported desiring an average of 5 or 10 minutes longer respectively. So, take a look at your partner. Are they smiling? If not, it might be time for a conversation about sexual expectations and needs. Because, ultimately, it doesn’t matter what study group survey subjects think, or what your friends, neighbors, or professionals on your computer screens are doing. What matters is self and partner satisfaction. That's something to keep in mind as you check out this video where Julia asks the question “How much sex should you be having?” So, are you sexually normal?
