Hitting Curvix Good?

So I can honestly say the worst pain other than my first time having sex was when my bf hit my cervix. Ya know the "hitting a wall" in your vaginal feeling. Hurts like a bitch and happened 3 times so now I have this issue where when I get too aroused during sex I think my Curvix is going to lower and he's going to hit it so I stop him before it happens causing him to get soft again and me sad about it a little but I talked to my bf and a friend I have that's a boy and they both said that they thought hitting the cervix was the goal in sex and when I constantly see pic that dudes post on ig about hitting a girls cervix like it's a good thing so can someone tell me if it really is a good thing because it Hurts so bad but why do they think it's the goal and what will happen if they keep hitting it?
