What Is The Treatment For Sexual Desire?

Hi, I'm 13 and me and my boyfriend made out for the first time yesterday... He got an erection and I liked it... I wanted to see what I could do but he left... I don't want sex but I want to do something.. What should I do? Is this normal? He is 14. If this happens again should I ignore it or do something?.... Is it normal to fantize about him?,....
