1. In my experience women talk about men and sex when they are together in much more detailed and explicit terms then men EVER do. The average conversation between two guys about any given women is about two words. "Nice!" "Yeah." That's pretty much about it.
2. A woman will not necessarily break up the boys as fast as a boy breaks up the girls. Guys share, women do not.
3. Yoko Ono gets a bad rap for breaking up the Beatles. She didn't. Ringo and George had already walked out of the White Album sessions on separate occasions (hence Eric Clapton playing on While My Guitar Gently Weeps) and that was over Paul being 'bossy' as they said, "->-bleeped-<-" is the more American term for Paul's behavior then, and continuing to this day. Paul wanted to make another movie and had even signed papers, the other three did not, hence Let It Be, a third-rate 'documentary' that fulfilled the contract so Paul didn't get sued to hell and back, but it's obvious to watch it that none of them cared by that point. John by that point wanted out, he was getting death threats on a constant basis, and as he said numerous times he had other things he wanted to do that the rest did not (and that went for all three of them, George in particular) and it wasn't possible to like make more money from the Beatles as they had all made more then they could ever spend as it was. It was really Paul who when he sued the other three to get total control of the group and it's finances that ended it.
So it wasn't some broad (and Linda was much more disliked than Yoko by the others), it was, as it always is in business, money - and not just the money, really the CONTROL of the money.
