There is a gay in every family, afterall.

I wouldn't worry too much about whether or not he masturbated about you when he was 13. Those kids will masturbate to just about anything, so you shouldn't take it personally.

Gays are all about the mouth-fondilng of minors.

The fact that you're freaking out so much about it doesn't really support your comment about being okay with homosexuality. If he does start to act like his gayness is the only mentionable characteristic he has, then tell him it's damn annoying and it would be even if it was him raving about being a blonde or liking anime or knitting.

Also, you might have the gay now, too. Go have gay sex with as many men as you can to check yourself.
