An opportunity has come!

Well then,
I got an invite to 'star' in a pornoproduction this saturday. Always dreamt of trying this some day, but now a bit nervous to participate. It's stated clearly in the mail I got that 1/ faces will be recognizable and 2/ if the male actor doesn't 'deliver' then no pay.
So a/ should I go for it? and b/ any advice on a 'stagename'?
Have a wonderful week all!
