Is it a choice?

It was hinted to me by a fellow TA the other day to come to her class and speak on being gay. First of all I have certain misgivings about that...not that I have a problem with my sexuality or the fact that the entire world knows...but sometimes I feel such academic discussions lead to a sort of tokenism. Anyway, I politely declined for the simple reason that the class is at 8 in the morning. Seriously, who's gay at 8 in the morning?
