Don't blurt blurt splurt but kiss, caress and wo her. The, fuck her slowly. It maybe your first time, but you don't want to be labeled a 1 shot wonder do you? All your mates will take the piss!! Even so, at that drunken party, coming out of the bedroom after 30 minutes has far more cred then 30 seconds.
So remember boys and girls, if your going to fuck, have a good fuck."
