My girlfriend/sub of over a year and a half now was formerly my "best friend" for several years. Like your situation, she knew everything about me including my sex life. If I got laid...she was my first phone call to tell about it uncluding every detail.

I used to think she was a bit of a prude...until we started dating in the biblical sense! She is the perfect woman! A saint in public and a complete slut in the bedroom! And a pain slut at that!

We are still experimenting and learning together on limits...but so far I'll be damned if I can find one.

Anyway, if you are looking for ideas you came to the right place. This was the first stop I made when I realized she had an interest and I learned much from these forums.

If you're looking for advice...mine is to take it slow and easy. Better to keep testing/pushing/increasing limits than to exceed them.

Just hang onto your balls! Its the quiet ones that'll fool you everytime!
