Why don't you try meet up with the girls who just want to be 'freinds' to start off with? Trust me they are only saying that just in case they don't actually like you when they meet you in real. If all goes well than the 'freind' can very quickly turn into GIRLfreind. Just gota play your cards right.
Using prostitute/high class escort services isn't such a bad idea either. Maybe that will get you the confidence that you need??
