It depends really how it is put , but i think that i would do the same toothpastekisses said, i always do it (not always sucefully)
but i dont really know , since i never get a date...
The best thing is to be yourself. If someone's like it good , If someone don't better luck to them.
I'm not telling you shouldn't fight SA, you're not your problem, i know it because i don't show/do many things because i'm afraid with no reason - SA - if you think you need to get more confidence in yourself, go get it.
I'm also not telling that the girl is kicking you, i don't know, what i know is that rejection happens and we need to deal with it.
OFFTOPIC: i don't know if i would always get a date, i can't invite a girl to go out , for the sole porpouse of analysing if she fits me or not. To me it looks imoral, She's a person as alive as me.
