I'm not a native English speaker so I'll be brief. Sorry for mistakes.

I used to suck with girls. Now I have worked on that and I don't suck anymore. I just started college and I'm talking with many of them. We could say I'm quite popular but there are all "friendships" . I don't know how to escalate (it's easy to do in the club or in a bar where you can touch her, dance and stuff but I talk to them in college). I know I should ask them out somewhere but I don't know how to do it without seeming needy. I already have phone numbers.

Edit: Also, a big problem is that when I talk to them we're in a group. I never have the chance to isolate. Again, all of this is easy in night game but Idk what to do in this setting.

Thks.
