This I get! She has feelings for you so it's easy to imagine, want, or need to be sexually intimate with YOU! While she prefers sex in general with men, she also enjoys sex with you because it's with YOU. Just accept what she's saying and don't keep brow beating her to explain it over and over again. There may never be an explanation you fully comprehend. That doesn't change the fact that it just is and that's part of what makes her special.
