For me, it's probably a holdover from my teenage years as a socially awkward and horny boy. I'm in my 30s now, but there's weird mental habits and impulses that are still sticking around.

I'm happily married, I don't cheat, I don't want to cheat, I'm really not interested in the "hot woman," but if I end up talking to her under any circumstances, there's a loud chorus of voices in my head screaming "dontfuckitupdontfuckitupdontfuckitup." I push through and get over my initial nerves, because I'm a grown up, but it's awful and annoying and I wish it would go away.
