Nothing turns me on anymore?!?!?

I am a 15 year old girl and I masturbate and watch and stuff everyyy day and I love it. It feels great. I used to have s and would turn me on all that. But I met this guy and I REALLY like him. We fall asleep together, wake up together, talk all the time. He listens to me. He gets me. We are always on a video chat because he lives 10 hours away. And I have never felt so close to anymore. There's so much More but I thought this could be why I'm not turned on anymore! At all! I watch for hours and still. Nothing. This sucks! And he lives 10 hours away and I can't stop talking to him, I like him too much! What do I do?! I'm too young for menopause! Not on birthcontrol, not on my period, not doing anything irregular. Help me.
