I 19F ,dating 20M for around two years, don’t really want sex anymore and I don’t know why, is this normal?

my boyfriend 20M and I 19F have been dating nearly two years now and I’ve realised I don’t really want sex anymore. we used to be quite active and it was really fun and I had a great time so I’m confused why now it seems yucky. Ive always seen sex as kinda gross and thinking about it weirded me out, I thought I was asexual maybe but I lost my virginity to my now bf and it was so amazing. I also never enjoyed masterbating and always felt kind of yucky afterward, even though I’ve been Brought up in a very normal way around sex.
this past year we’ve been long distance bec of him being in uni, it’s been fine just lonely. He’s been down for a month a few times and I’ve gone up to visit him, and I feel guilty I have no desire to have sex. Only once in half a year have I wanted it and I’ve talked to him about my lack of drive and how I feel bad but he says he’s okay about it. I doubt that as he sometimes makes off color comments about us not having sex and I know he wants it. I also haven’t liked being touched sexually in any way, whenever he touches my boobs I get uncomfortable and normally stop him.

I have depression and I am wondering if that’s the reason, but I’ve had it our whole relationship and I had a good libido. I also am neurodivergent and just recently got diagnosed, I find I get overwhelmed by touch easily. i love him so much he is my first proper boyfriend and he has been so good to me and respectfull, obviously we have our differences and arguments Which is often around him not opening up or my low mood. i think we have a good relationship and we both trust and love each other so much. He has introduced me to most of my new friends and they are my closest friends ever( which is why I came here instead of to my friends). I think we have a good relationship but I don’t know because I have doubts when we argue and his immaturity with money. I’m not sure if this is normal, will it pass or is it forever idk what to do. Please I need some advice and help I’m freaking out a bit.
