Not attracted anymore but loving him

Okay so i’ve been with my boyfriend for two years now. At first, when we began to have sex, i was very excited by the idea of making love with him. But recently, i feel no sexual desire when i think of him. I still like when i have intercourse but i’m not going to be excited or attracted by him. I used to be excited by the idea of him fucking me but now it’s just meh. I’m actually shaming myself because i prefer to masturbate and think about men who turn me on. I feel so disgusted by myself because i’m not able to want him. The problem is that my love for him is very very strong and i don’t want to dump him just because i have no sexual desire for him. I love him from the bottom of my heart and we’re living an absolute dream if i don’t think about the sexual part.

I know that if i talk to him about my problem he would be devastated because he’s so attracted by me.. why am i not???? What can i do!!!
