bleeding after sex

Okay so I'm with this guy and like he has a really big penis, I've never had anyone so long, and I know he hits my cervix, he knows it too it always happens, but it doesnt hurt to me it feels like amazing. But after we are done I bleed from him hitting it. He is pretty gentle at first because he is aware of the problem and tries to take it slow, this problem happens often to him so he goes slow then eventually starts to speed up and get into it. But I don't feel any discomfort, when he hits it it feels really good, like best sex ive had but will the bleeding stop eventually after we have sex more?? Like will my cervix get use to it and stop bleseding or can that damage my cervix??? There is normally enough blood so that it's seen on the condom but it stops as soon as we stop
