HELP 18yr old virgin needs help!!!

​Don’t wanna end up like the guy on 40yr old virgin. I just can’t seem to get laid. I mean I’m a chill guy, somewhat good-looking, and play sports but all the girls I’m around just see me as a friend. Why is that? No matter what I do this happens. Any advice so I can get laid asap especially since I don’t want to go to college a virgin. 

Thanks bros
