I'm a straight male and i like to suck my male friend's nipples?
Okay, so here's the deal. I'm 18 years old, absolutely 100% straight, am in no way interested in men, I'm an athlete, I get good grades, etc... But I have a problem. I have an equally straight male friend who is an athlete on the same team as me, and he gets even better grades, etc. For some reason, we get this uncontrollable urge to chew on each others' nipples and hair (on the head to be specific), and make suckling mushy noises on each others necks (with very little contact). We'll just be sitting next to each other and I'll start gnawing on his hair or his nipples like a rabid dog going to town on a bone, and he seems so receptive and equally eager to reciprocate! Is this normal?
