It's funny because I've never really dated anyone who wasn't a gamer or a cosplayer. I think I might be okay with it. As long as he gives it a chance and doesn't try to stop me from doing it, it would be fine I think. I'd prefer they be into it like I am, although currently as that is the case the majority of my cosplay that I do now is pairings unless I'm doing a cosplay with my BFFs. Which isn't to say a bad thing but there are just some things he wants me to do, and I'm not exactly excited about it...
Planned New Cosplay for near future (in order of listed):
