Need some advise getting a gf?

It sounds like you just want a girlfriend because most of your friends have one. Don't sweat it. I didn't have my first "girlfriend" until I was like 20 (I mostly just hooked up with girls between high school and college). It didn't bother me though, I was like you where none of the girls my age really interested me. Don't force yourself to try to date someone just because you want a girlfriend, having a girlfriend that you like is tough enough as it is, lol.
