I believe that there are many men/women cheating physically on their partners. For me, I absolutely love my gf. But then there's times when we use the wrong head to think. After the deed is done, guilt sets in. You then tell yourself you won't do it again, but it seems impossible doesn't it? Haha. We console ourselves by thinking that cheating physically is better than cheating emotionally. But in our hearts, we know its equally bad.
Just sharing my thought.
Cheers!
