Everyone I've asked other than DH hates my name for a boy Tristan. I don't really care. I like it. I say if you like it, go for it. I knew a girl named luna when I was in high school. Of course I went to HS in NYC and we also had girls named passion, cookie, candy, buffy, moona and a bunch of other names that arent exactly typical. Just go with what feels right to you.
