i feel u, im 20 and single too
ive had my girls before, and i just talked to this pretty hot bish at the gym today
the way i see it is... theres plenty of time left in ur life for u to get girls, so just takek it easy and dont rush yourself or you will probably be nervous or not know what to say around them, just meet some girls and start up a convo and let it go from there
and bein drunk helps a lot lol so find some parties!!!!!!!
dont worry u will find someone, but it wont happen overnight necessarily so be patient.
/2cents
edit: find some places that they will be at too to speed things up... ie. gym, mall, parties, etc. or the easiest way... get one of ur buddies GFs to hook u up with one of her friends
