It's ok - you're entitled to your opinion the same as anyone else. This is for the most part a forum for discussion and debate and if everyone felt the same about every topic there'd be little point in posting.
I have to admit fucking friend's husbands without their knowledge is a betrayal of their friendship to some degree and the fact that I get a kick out of it probably makes it even worse.
In my defence I've never been responsible for the breakup of a friends relationship and I've never wanted to make it about more than just sex. I could argue that any husband (and not just the husbands of friends) who is willing to fuck me is just as likely to cheat with someone else and at least I'm not going to try and steal them or get into a relationship with them. Most married guys who cheat just want a discrete, no drama, no come back fuck and that's what they get with me xx
