Boyfriend doesn’t want to have sex anymore. HELP

So my boyfriend and I used to have regular sex, once or twice a week. But one day, I had him over when my parents weren’t home, we are in high school. It was the best sex we’ve ever had. I sucked his dick, then we fucked for like 25 minutes, he came twice😉. And then afterwards, he ate me out and fingered me until I came. And it was the best orgasm I’ve ever had. But now he won’t do anything to me, finger me or anything. I don’t know what happened. We haven’t done anything in TWO months. I’m going crazy. I have a crazy high sex drive, I’m always horny when I’m with him, but he always turns me down whenever I try to do anything. What should I do? HELP!
