you'll be ok. I don't go on dates really, cause I'm not looking for a gf right now. If she doesn't work out there are always more. I meet new girls on the street or where ever everyday, I hardly call them though. I actually won't give my number out like that, too many people will call me and I get to concieted and end up starting to miss work because I start thinking my personal life is more important.
There's only maybe 2 girls that I would settle down with. One doesn't want anything more than the dick anymore, she used to want more but its a long story.
The other one is mad because she says I'm a slut and I'd have to stop before she ever thought about a relationship with me.
But as for you don't even be nervous, liek I said there are others out there, just be you, if she don't like it tell her to go to hell.
