DjDan said:that shows desperation. the minute you pull that on a girl you will lose. i speak from experience. i must have lost at least 20 girls last year due to that little stunt.
its best to ignore her.
'ignore, ignore and you'll get your wh0re.' =)
Its only desperate if its coming from a place of desperation. If OP had other plates that were giving him sex it would be coming from the place of.....i have x amount of time, i want to have sex, if your not going to do it then leave and i'll call someone that will, theres no emotional reaction on his part. He isn't mad, frustrated, desperate, he just has specific needs as a man and values his time.
Not sure if you blew that 20 girls out of proportion or what, but you must of been saying it in a desperate needy way or something to be losing girls off that. Girls know they have to give up there p*ssy if they want a guy to stick around. I'd recommend you read the book titled MODEONE
