You can be as girly, or not, as you choose. I don't know of any areas in the SCA that would restrict what you could do based on gender. I've known quite a few women who put on armor, grab a big stick, and go out to beat the ever-lovin' hell out of the male fighters in the ring.
Just so you know, Royalty for each kingdom changes hands every six months. Three months after the King and Queen are crowned, there's a tournament to see who will become the next Prince and Princess. Normally, a man fights for a lady in the tournament. However, there's been at least one Queen who fought for a man in the tournament, instead.
So, yeah. No gender-based restrictions on activities.
