Boy problems help!

Allison
So I'm totally falling for a guy. He's never had a girlfriend and is scared and quite shy. He's used to partying with his buddies and hasn't been chased by anyone. I'm 21 and he's 19. He admits to liking me a lot. His best friend said I'm the first girl he's falling for. But how do I get him to loosen up and commit? We see each other every other weekend with friends and kiss late at night when everyone else is leaving. Tragic romance, help.
