What should I do? guy 21 and I'm 17 turning 18?

Hey! When I was 131/2 I was 90-60-90 cm and 169cm tall and I always had older men coming on to me and I mean "older",as in their late 20's and 30's.From my experience he sounds like a bit of a sleazebag.Besides if you are not yet 18 it would be illegal for him to get into your pants.The best thing is for you to go with your feelings.Your subconcience is trying to warn you.Listen to it.
