I need help with bottoming part 2

So idk how to use Reddit so this might be stupid but forgive me🙏🏽.

So this is kind of a follow up to my first post, where I asked for tips on bottoming since it’s my first time and bf is pretty big.

I need more tips, position (that don’t include dildos cause I can’t buy them rn) cause he can get it I’d say 3/4 of the way in but there’s a point where it does hurt when he tries to go deeper? Idk if it’s really pain or if it’s normal or not? Any tips are a huge help🙏🏽
