hey gurls

So i am one of those mature sissies. I happen to have a group of girls who are friends. Now the issue is they have asked me to join their gurls night out this weekend. There would be no other male for the party. I have been a closet sissy all my life.

Now i am paranoid as to why they have invited me. Do they secretly know i have feminine desires? or is it just that i am friends with them.

I have decided to go anyways. How should i behave? i mean i have never been a part of all girls parites. Now if they know my secrets, will they give me some hints to confront me?What would they be? Should i pick up on them?

I am all manly out of the closet so what made them guess my sissy nature. if they do know about it?

There are 7-8 of them of which i am closer to 2-3. The question of them abandoning me (if i confess my sissy side) does not arise.

I am totally confused.
