Controlling Myself in School

I keep having strong urges to make out with this boy in my homeroom in high school. I just want to walk up to him and start making out hard core. I don't even fantasize about sex, just kissing hard and being so up close, body to body, because he's SO CUTE. I keep thinking about him all the time and try to run into him in the halls. I think about him so often that I'm distracted in class and when doing homework because I'm making up scenarios in my head. Ughh he's so cute but we've never talked. Most of you will tell me to just talk to him, but I'm busy with school and don't have time for boys, so how do I get over my urges?
