Ask him urself as he may say hes not or not answer honestly if u get a friend to ask him, try on msn or txt him

no.
because if he texts\messeger theres proof he said it...

Hmm toughie, if he went out with a guy then that would be a giveaway?

If not you could ask him?, if he was in denial ask subliminal questions like who is your favourite singer/band if he says something like Justin Timberlake or The Backstreet Boys.... well go figure.
