Embarrassing question about sex 😫

It’s my second time having sex with this guy and his penis hurts a lot when it goes it, and i feel like my vagina rejects him because it keeps pushing him out. idk what to do, i try to relax but he has a large fucking penis.

it’s also my second time time having sex ever so maybe it’s because i’m not super experienced?? any advice will help!

PS, we used a lot of lube and tried different styles. i tried to ride him and it was hot but it hurt a lot and i could only do it for a little bit. i also mostly feel pleasure when he fingers me, but not yet during sex.

advice needed.
