women talk about it all the time amongst themselves... Their husbands or boyfriends penis size, shape... whether the guy can "perform"... and THIS is what they mean by perform. Whether he can hold himself and get the woman off first. The vast majority of men can't perform in this sense. More women would experience true vaginal orgasm if their men could really perform. When a woman finds one who can - even a married woman - she will not be able to resist going back to him again and again.
