Always with the 🍑

I've never really been a fan of the rear door and none of my previous partners where into that either but my current partner just can't get enough. Every time we go to have sex things start off well then he say "let me put it in your bum" and it kills the mood. I know it's normal and people do it but the few times we have tried it's really hurt and I just can't get into it. It also makes me feel like he doesn't want to look at me. I'm not fat. But I'm not a crop top gal either so when he does this it always makes me feel sad. Is there something wrong with me or why does he never like the 🍒 always the 🍑

Please help me!!!!!
