What do I do?

I have been with my boyfriend for a year. I love him deeply and I know that I have finally found someone who makes me whole.

But when it comes to anything sexual, I have to think of girls for me to reach orgasm.

I feel horrible about it. But his body doesn’t turn me on. I never save any of his nudes, and I have never masturbated to the thought of just him. His body is beautiful and he’s unreasonably attractive. I just can’t finish without fantasizing about girls, even when it’s him who’s literally eating me out right there.

I feel like a bad person. Kissing him turns me on, and geez him doing things to me turns me on so much, but I can’t get any satisfaction unless I’m thinking of women.

I’m not sure what to do about this. Please help.
