How to manage sex drive?!

So,i'm 19, virgin,but it seems i'm always horny,sometimes to the point where i can hardly take it.My giy situation is complicated...there's a guy i fool around with but he doesn't give me nearly enough,like maybe one session in three weeks.I masturbate,likle five times a night or more,but it doesn't take care of that urge.I just get so worked up,i feel like i must have sex,like i need it,and the fact that i'm not getting it frustraits me to no end and makes me feel so deprived.Maybe i have an over active sex drive,i don't know.But anyways,what are some ways i can help myself not get so upset,sadisfy myself,or moderate my sex drive?
