Sorry but as an expert in the one night stand department, I think your stories hilarious, as I used to do this as well, then i got to the stage one the deed was done I just used to say " Look! you do know this was just a one off, I'm going to leave now, don't bother asking me for my number as you won't get it and consider yourself lucky." and get up dress and leave. You should have seen the looks on most of the guys faces t was like you had just done them the biggest favour in the world.
