Focus more on the feelings and the love/etc., because your first time will SUCK. hehehehe... it's just the way it normally goes. I have never heard of anyone ever having "great" sex their first time. Great by atmosphere, maybe, or by feeling... but not by the act itself.
So, enjoy... but don't put too much stock in the act- after all, the real joy is in practicing over, and over, and over... hehe
