Wow...fascinating responses. But....
I noticed in the initial thread that you mention that he knows all about your being CD. I'm wondering why you would say that if you are going out en femme. Does you statement imply that you are NOT going to be en femme?
Also, if you are asking for advice (and there is some good common-sense advice in parts of this thread) might it be that you hadn't thought this out before you accepted the invitation?
My advice echos Sally's: know who you are and what you want, make that clear to your date, and then have fun!
