Soapstar,
I suggest you talk to him about everything and make it clear that this isn't a deal breaker for you and that you love him still. Open communication is probably the only way you can go to get on the same page as him.
I suggest you also pick up the book "My Husband wears my clothes" by Peggy J Rudd and it will give you a perspective, from a wife, into the world of crossdressing. Not every crossdresser is the same, some have certain flavors they like and know where they want to set their limits at.
As it was previously mentioned, once you get to 10 posts you can join the GG forum on this site! Good luck!
