Nonexistant sex drive

Hello everyone. I've been struggling with a near nonexistant sex drive for years. I'm 17 and the last time I was actually aroused was sometime last year. In January, I think. I just can't seem to get there even when I try and it's making me feel as if I'm taking something away from my partner. I've tried natural aphrodisiacs but they just don't seem to cut it for me. Does anyone have any tips or anything that could help me?
