So my boyfriend (he is my first/only boyfriend) and I have been dating for a year now, and I am super in love with him. At around 5 months we started to do “stuff” (not sure how best to put that). For a while I had a very high sex drive, and I loved doing things because it made me feel closer to him. In the last two months my sex drive has basically disappeared and I have no idea what happened. He thinks he did something wrong, and I feel so bad because I don’t what him to think it’s his fault! I just don’t want to anymore, and I’m not sure why. (This is very recent, before we even started dating I had a high sex drive, I would masturbate and that helped a lot with our communication because I know what I like) The last time we did something, I let him go down on me, but I got a little freaked out and he stopped right away and we just cuddled. He’s always very understanding when I ask to stop something, and he never makes me feel bad. He also always asks for consent before we start, so he’s doing everything right, I don’t know what’s wrong with me. What causes a decrease in sex drive in young people?? (I’m 18, shouldn’t I be at my prime!)

Ps. If anything I am more confident now, because until about a month ago I was insecure about his ex gf of two years whom he had sex with. I’m a virgin and just felt super uncomfortable about his past. But after a long time (of talking to him about it as well as getting advice from my mom), I have become okay with it, and trust him very much. I feel like that should motivate me to want to go further, but it doesn’t. :(
