That should be done somewhere private, not the men's locker room in school where the gym teacher can walk in on you. Do that in like a hotel, not a bathroom, especially a public one, unless you have a large one in your own home where four to five people can fit inside, and nobody else is at home, but pretty much, it's guys gathering in a circle masturbating.

No, I haven't tried it, and hopefully, never will; to me, it's just something that straight guys do to overcome homophobia. It's not that I'm homophobic, I'm not; it's just something I rather do in private by myself.

If you want to go, that's your decision, but I would'nt recommend it if it takes place in the boy's locker room in school.
