Why Do Some Men Cheat?

I decided to write this because of what a friend of mine has gone through and is still going through in the hands of these wicked men. Times and times again, she has been jilted nd I cud not help but feel really sorry for her. Maybe she's just not lucky with men.

Seriously these men deserve to be castrated with a pepper flavoured knife. What in the world can justify a cheating boyfriend or husband. I am not in any way implying women do not cheat but that of men is just too much!!!!

I was watching MomentsWithMo on Ebony life TV where Moses, a past Nigerian Idol Winner stated that men cheat cos their Gfs or wives stop doing what they used to in the beginning. Like what does that mean? I think that just flimsy excuses. If i'm not doing somtin right, he should be able to call me to order not use that as a cheating avenue or what do you guys think?
