I am wondering… What does it make you feel like wanting to fuck someone else besides your partner? Is it ovulation? Is it alcohol? Is it work trips? Big dick? Shaved pussy? Someone elses sexual experiences? What makes you desire someone elses sex?
It can be literally anything. A look. A smile. A handshake. It's feeling the attraction and not ignoring it. It could be a kind word; a hug; a funny joke. I know that I can't pick anything in particular...
