Ok wait ... is doggy style meant for anal sex? What am I missing here? 😂

When my partner and I do “doggy style” I have to arch my back and he puts it into my vagina, not my bum, and it really hurts me. It hurts in my stomach and really hurts my bum although it’s not going in there and I feel really hurt and uncomfortable afterwards. When he’s about to cum he’ll go really hard and fast and the pain is actually unbearable. It sends shooting pains to my bum and stomach and it really hurts. This position is not for me AT ALL :(((
