I was pretty young when I realized that I was into other guys. So, I went around looking for the guys like myself. Only one of them was really into wanking together. All the other guys (and I, too) were into more satisfying stuff
Once you go into all the trouble, and take the risks involved you may as well want a just reward for all your toils.
A few guys I know shared their stories about their beginnings. Wanking together featured prominently as something that was not too gay since so many str8 guys did it, too. Like it or not, mutual masturbation won't make anyone gay or str8 or anything in between. It is a mild form of situational homosexuality known in many cultures over a long period of time.
