Then lay it all on the table. Talk to her.

I don't think it's that big a deal being you guys are only a couple months into the relationship... she's probably just pretty shy. It sounds like you guys just haven't even really got to know each other yet, know what I mean? Almost like your friends set you up and you guys just decided "Okay we're dating."

I think a small little trip away together, like a mini vacation somewhere would be great for you! It would give you guys a lot of time to spend together and get to know each other better!

Otherwise I'd suggest just talking to her. Be honest, man.
