I was listening to this human sexuality talk show on satellite radio the other day, and this girl was lamenting the amount of time (15-20 minutes) that her boyfriend pounded her before finally cumming. The host therapist was saying it's a popular notion that guys get from porn videos that women like to be fucked for long periods of time, or that it makes them look more "manly" if they can do it. In fact, the host was saying, past a certain point, many women really don't like it, and seemed to suggest that most of the time, anything much past 5 minutes was just too much of a good thing. So, the question to women on here: For what length of time, and assuming you like/love the guy and he knows what he's doing, do you enjoy sex, and at what point does it become "geezzz, can we finish already?" or boring or annoying or painful? I'm only talking about penetrative sex, not the total lovemaking experience including foreplay, etc.
