<human>: Throwaway because she knows my username. 

My girlfriend is wonderful, she's  kind hearted, has an amazing personality and is beautiful. She's everything I could ever want in a women and she has done so much for me in these past months and I truly love her. 

There's one problem though, I don't feel a physical attraction towards her. I know she's a gorgeous girl, she's in perfect shape yet has some curves, she takes care of herself and whenever we go out I always notice men staring at her. But for some reason I can't feel that sexual connection with her. Don't get me wrong, the sex is good, but theres just something that's off. I feel as if I'm stringing her along by staying in the relationship but I can't bring myself to end things with her. 

When we first started dating everyone was completely shocked because I've only ever dated black women (we're both white). But I always told them its not about race at all. But I'm starting to think that might be my problem with her and I feel horrible even saying that. I've always been attracted to dark skinned women, Afros, natural hair, curves. I watch a lot of porn with black women. But I always felt that if I found the right woman, the color of her skin wouldn't matter. 

What should I do? Should I be honest with how I feel and end the relationship with her? Or do I keep moving forward in hopes of the attraction growing?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: White male not feeling a sexual attraction to my white girlfriend. Think it might be because I've always been more attracted to black women. To end relationship or not?
