GUYS: Long distance relationship.....Do most men cheat?

Well my bf and I have a daughter together and due to financial cirumstances and a few other issues we were dealing with I was forced to move to GA with my parents and leave him in FL....When i left we WERE NOT in a relationship. However a few months later during a visit home we got back together back in OCT(i moved from fl in Aug). My boyfriend and I are both 20 and he is very fit and handsome...I want to believe that he is staying commited to me but at times I wonder....ya know with him being so young..hormones raging..Do all guys who are in long distance relationships eventually cheat on their significant other? I mean I come home to visit like once a month and I move back the end of July....
