HELP! I don’t know wht to do 😭

Okay y’all, so everytime he hit it from the back I end up bleeding. Like medium/light bleeding.He started of slow and silly me told him to go deeper.. It doesn’t hurt when we do it that way but any other way I never bleed. And he also said he didn’t go all the way in so idk. We both been tested and I just don’t know wht it is. I’m on the pill junel so idk if that effected anything. Any advice?
