Crush on my seminar tutor - advice?

Okay, guys.

I have a rather big crush (infatuation is probably a better word) on my seminar tutor. I'm a first year uni student (i'm 21, so a little older than most first years), and i'd estimate him to be in his early 30s. I suppose the infatuation has started partially out of a desire to connect with someone (i'm struggling to make friends in uni), and he pretty much fits the bill (slightly older man, similar interests in certain areas of our subject, and in my opinion, adorable). Obviously I only know him on a professional level, so he could be completely different in his personal life. I would love to get to know him on a more personal level, but I don't know if this would be possible or appropriate. I don't know if he's in a relationship, if he finds me attractive, or if he's even straight. And even if he was single, most educated uni professionals I suppose are not interested in young and inexperienced students. But i've fallen for him pretty hard. I don't want to push my feelings or make them more known, as I don't want to ruin our professional relationship. I'm so shy, and just starting a small conversation with him would be nice, but I don't have the courage. I'm just pretty confused and conflicted.

Advice?

Was in a similar position, but I decided not to go for it since there was a lot of competition from about 15+ other girls vying for his attention at the same time!
