That would be my age (20). I work a job that has me rubbing elbows with older women, many of whom are definitely doable. Also the last three pickups outside of work were all 23+. The problem is I occasionally get dropped once the subject of age comes up. This usually happens when I'm invited to a bar/club/concert that's 21+. So I guess I either need a way to A. avoid the question/situation coming up, B. lessen the impact it makes, or C. sink them in quick enough for it to not be an issue. Any ideas friends?

TL;DR: how can a M[20] pick up/keep women aged 21+?
