Lots of sex dreams but I’m never in the mood?

Hey, looking for some advice?

I’m 19 and I have been with my boyfriend for just over a year and I love him very much. When we first started to become sexually active, he was my first partner for any kind of intimacy and I was always turned on and excited because it was always new. Lately I never feel like doing anything, but I have lots of weird sex dreams and sometimes orgasm from them. I’ve been really stressed and had low self esteem for a long time as well, so I think that might be why I’m so turned off. But how do I fix it??? And why am I still having intrusive wet dreams with a super low sex drive?
