Thank you for being such a service to the public, MissSalacity.
In addition to liking men who are good-looking and entertaining, you seem to also like ones who are total arseholes who cheat on their families.
They're very lucky their wives don't find out and take them to the cleaners, not very lucky to find you.
As for thinking that all married sex is bland, well, you don't know what goes on in peoples' homes, do you (I was going to say bedroom, but why confine sex to the bedroom just because you're married, eh?)?
People who cheat are liars, and I would know, because I've been a mistress and cheated in relationships, too.
So yeah, they'll act the repressed male so you'll get kinky not because their wife won't take it tied up/from behind/use toys, etc, but because they get off on that with anyone and it's a way to get you to be kinky.
So stop deluding yourself that you're some knowledgeable madame helping them open up into flowering sexual creatures. They're in their 40s - they've been around. And if they can lie to their wives, they can certainly lie to you.
And anyone who screws her friend's husband is a sad twat, not a cool cat.
I mean, ffs, there are enough men in the world that anyone with half an imagination can seek out elsewhere.
