Yes we have all done it in our early days of growing up as it is just part of learning about our bodies and sex.
But lots of us still like to do it right through life but don't always get the opportunity. I am sure we would have jackoff experiences with other guys a lot more often if there was chance to do it.
It doesn't make us gay or bisexual or whatever label you want to put on it - its just sexual relief - Kinsey said that there was a sort of sliding scale between Homosexuality and straight - and there are lots of us who are somewhere in between so we cant put ourselves into a definite slot.

Just enjoy your sexuality guys whatever sort of sex you like!

When I was 12, me and my buddy were in his basement playing a board game. My buddy who was 13 asked if I had ever seen a playboy magazine...I hand not to that point. He proceeded to pull of a stash of porn magazines that were his dads. As we gazed at the pics I could see we were both boned up...he then asked if I had ever jacked off...I told him I had. We ended up beating off together looking at old porno mags. We did this daily for years...my first cum shot was with him looking at pics of hairy 1970's pussies in playboy....fun times indeed.

My friends wouldn't even talk about sex let alone consent to jacking together. It was a taboo subject, besides the fact that if anyone found out, you could have been killed. It was a really conservative area.
