Should I at least try dating men?

I've been a lesbian since before I knew it (Ember Quade from Squirrel Girl and Miss Marvel changed me, okay?) but I've only ever dated one girl, and the farthest I got with my middle school boyfriend was hand-holding, and now we're each others' gay friends. But there's this guy that's one of the stars in the play at my local theatre, and I'm working the lights. We went out to dinner with the rest of the cast and crew, and the whole time he was making jokes directly to me and then hung back afterwards to talk to me some more. I'm pretty sure he was hitting on me, and having been lonely for a while now, I've been thinking about asking him if he wants to go out. I don't find any men attractive, but he's funny and kind. Would it be stupid to even try and go out with him?
