Not while he was in the White House anyway. I think he's too careful to slip up like that. Now that he's out of the White House there's no telling what he'll be getting into ( Idle hands is the devil's workshop).
But believe it or not, not all men cheat even if they have the opportunity to. I know a couple of guys in their 30s that I'm really cool with and they both swear they've never cheated on their wives. One of them goes out every now and then to bars and he'll strike up Convos w/ chicks and will even dance but he's never actually cheated. He's 36 , college-educated , black and has been married for 10 years.
This is me. I won't fukk around on my girl.
1. Cause I've had more than my share of puss In my teen/20s/30s (35 now).
2. Got 2 kids two baby Mama's and both cool with my girl.
I don't have the desire to cheat. Most of my homeboys that used to have stopped cheating on there chicks as well. We all have either jobs or businesses and kids and no time.
That said I got a few with all of the above and still step out from time to time.
I think Obama is the latter lol
