/nods to the lurkbastids
friend of mine here simply didn't "get the memo" for a few years. he's now bi, and i can now personally attest, a damn good kisser.
back to topic...you have no way of knowing his "true" sexuality. i bet he doesn't either. 11 is young...i knew i was hetero for a long time. ii didn't figure out my attractions to men were present as well until a few years ago. i trust people to work out their own sexuality...i just try to watch the enviroment for the pressure to conform.
