Is doggy style painful/uncomfortable for anyone else?

Doggy style is incredibly uncomfortable (borderline painful) for me. I instinctively raise my back so that’s it’s in line with my hips (instead of perpendicular like it is in doggy) whenever my BF and I try this position. If I’m laying flat on my belly and not bent over it stops hurting (still doesn’t feel GOOD, but doesn’t hurt). Sex in any other position is fine and feels great (though reverse cowgirl is painful in the same way). I feel like there is a compatibility issue with the angle of my vagina and my BF’s penis or something that’s making doggy style undoable.

Anybody else have this problem? This is not a lack of lubrication issue either, so please don’t suggest that. I repeat. This is NOT a lack of lube issue.
