crushhh help

Hey so I like this guy and he is really nice, he is my height (I'm so small), and my age. He literally so cute and we get along. We do a sport together after school and that is the only time I see him. Once a week for an hour. So we don't get many chance to talk but when we do we talk heaps and he constantly smiles and is curious about me. I think he likes me but I barely see him. Is there a way to get his number or social media without being weird or obvious???
