make sure you communicate with each other first about what you both want during the deed, and don't do anything unexpected or unwanted; the last thing you want to do is make things weird or uncomfortable by having weird porn addled fantasies. make sure you shower and brush your teeth before and after. no one wants to fuck a gross smelling guy.
remember after care yadda yadda and cuddle lots after and uhhhh foreplay that too lots of that before.
and oh yeah use protection too btw since you're retarded enough to post this on /b/.
