I've got an HB7 (might be 6.5 but she is very young to/for me), on Facebook. She accepted to date with me.
(Nowadays I'm not at home, anyway. and she lives near my home. also she was easy, probably because she is not that much attractive and I was direct)

Is it a good idea to date with her, in order to advertise myself among her friends? (close or distant friends, doesn't matter)

She is a bit cute but not that attractive.

(Note: I'm not known among the girls, and I don't have social proof)

I want to date with her with purpose to advertise myself to other girls, and also I don't want to date with her because I don't want to be seen as low standard guy. What should I do?
