I'm into some nerdy things that might be considered women repellent. Namely, I've gotten into D&D with some buddies, and surprisingly, I really enjoy it.

My question is, when I'm meeting women and on dates, should I tell them about that? Should I own it and say yeah I did this nerdy thing last night but I really enjoy it because of x, or should I avoid talking about it / pretend that I hate it?

I'm always uncertain how to approach things like these. If I'm overall a confident and attractive guy, am I going to repel a lot of women by sharing these things with them? Or is the fact that I don't give a shit about what they think going to be more attractive overall?
