I don't understand why so many people think it could possibly be anywhere near to being homosexual, when two or three guys are there to please a woman.
That's really weird thinking, in my opinion.
I've done it lots of times and there has never been any thought of homosexuality, it's all for her!!!!
As for accidental touching, so what, it's only skin FFS?
I gather from this thread, that many guys might have a problem shaking hands with another male.
Homophobia rules, apparently.
