Please help girls problem?

I'm 5'10 short black hair, Green eyes average looks if I'm honest to my self. I am athletic and I have a good body build because I go to the gym a lot but I'm not the kind of guy that flexes and shows off about it I keep my shirt on and don't take it off all the time. I play a lot of sport mainly basketball. I don't take any drug including alcohol because I am hopefully going to play basketball in college and I need every advantage I can get. I not a party person but I do like to have fun in other ways. I like to make people laugh and my grades are average. I enjoy comedy movies but not horror films because I would rather laugh then jump behind my seat. My fashion sense is average really but I don't dress like a tramp. Problem is I am clueless when it comes to talking to girls at my school (highschool). So do I seem like a datable guy from what I have told you and how do I talk to a girl I need tips I hopeless and I get nervous. My age is 16.
