Really wanna do one of these, BUT a bit shy! Do we do the biz in front of other invites???
If I had a fiver for everytime I've heard this said, I wouldn't need to work again. Almost every party newbie feels the exact same way, but thats soon forgotten (especially at Abbies parties). The girls are so warm and friendly, and will always go out of their way to make sure that your looked after properly, particularly if your new and they know your nervous.
As for being around other naked men (and that does bother almost all the guys before they get into the parties). The men are not interested in you at all, they are all far too busy having a good time themselves to be remotely interested in anything anyone else is doing so that worry is very quickly forgotten believe me.
Why don't you try one of the quieter parties to start with until your comfortable with it?
