Well, some of us don't know the story - other than what is posted here - while others know more about what transpired between any of them.
That said, man or woman a cheater is a cheater regardless of their reasoning as to why they did it. Men cheat, women cheat - it's like racism and saying that only one race is racist and the other is not, everyone has the potential to be guilty of such acts regardless of sex.
What you are implying is all bullshit for people to feel better about themselves by feeling better about their kind.
"A Real man" doesn't necessarily refer to penis size or penis skills - there are many things that divide a man from a boy and IMHO most, if not all of that is not an issue of sexual abilities. If fact assuming that it is only penis size and sexual ability is what makes a real man - not.
