Yuperoonie - you tell 'em.
Put it this way - I divorced for my ex's adultery (and I bloody well made sure that was the stated reason too), I'd never consider leaving someone over a pair of knickers (and bras and basques and nighties and make-up and...).
I can only imagine how many women must feel and I'll bet the stereotypical crossdresser must come to mind. Therefore, he's going to be gay and going to want to go off with another man.
This forum is about offering support to GGs and family members of CDs and perpetuating that myth helps nobody at all, especially not the majority of CDers who are good, decent, honest people. In fact, that's what it seems many GGs like about our CDers, that they're a darn site more open and honest than most men out there.
I suggest a sticky at the top of the forum aimed at wives/girlfriends to discuss their straight, faithful CD partners to ensure that this message is seen and heard regardless of whoever posts about proud they are that they can use CDing as a valid reason to cheat.
