Interesting scenario. So, this study date still hasn't happened? I'm anxious to know how it turns out.
A few things that some people have already touched. Definitely don't assume he's gay just because he's in ballet. Also, definitely don't assume he's not gay because he's in a Bible class. I actually took some religious studies and Bible courses in college specifically because I wanted to know what the Bible really says about social issues (such as homosexuality), and it was actually quite enlightening. I met a few other people who were also gay and there for similar reasons, so don't cross off the possibility that he may be in that Bible class for a reason like that. I know that I feel a lot more empowered now that I can regurgitate Scripture too to make the fundamentalists look like fools!
Good luck with the study date. It reminds me of when I was in college. A few girls (some quite hot) often invited me to "study dates" in their dorm rooms. It was mostly because they knew I was the class nerd and could really tell them what to study, but some of them wanted to get frisky with this nerdy boy...too bad for them...lol (it's a shame that it was never a guy)
