I'm married for over 15 years And lately I been thinking how it would be to sleep with another man is that normal

I think I was going mad but I love the opposite

It's very common.

There is scientific evidence that suggests everyone is a different shade of bisexual, some people just lean more one way or the other, and its all completely natural whichever way you do.

I've spoke to loads of married guys that suddenly become curious. The thing with men is we are more likely to wanna experience new things especially with our sexuality, we are more open minded and as we grow older we become less inhibited etc. So I say don't deny until you try, no one can say they don't like something they've never experienced, after all us guys know how to please each other because we've always had a point of reference in our pants all along lol

I KNOW I'm a str8 guy and I love sex with women! But I also love getting fucked by men and sucking cock, I don't kiss dudes or cuddle, but just like playing with cock....preferably big ones.
