I've been with north of 80 women. I've had some amazing times. I took a girl's virginity on a balcony overlooking a beautiful foreign city on a study abroad trip.

However, I'm older now and I've tried to be in "real" relationships. I keep fucking it up. I keep cheating, to be blunt. I keep getting the urge to fuck around. It's like, no matter how much we have in common or how great she is, eventually I will get tired of the woman I'm with and start to look at some other hotties.

Do you guys have any advice on not being a douchebag once you're actually in a relationship? Maybe monogamy is not for me, but my instinct is to hide my sexual history and crazy sexual impulses from whoever I'm with. I realize I'm a cheating lowlife, but I'm trying to figure out if it's possible for me to not be this way.
