Help, help, help!!

Hey ladies, my partner and I have been together for quite some time now and we have a very healthy sex life. I’m a frequent patient at my lady doctor and found out years ago that I suffer from PCOS. Moving forward into the sex part- I CANT DO DEEP PENETRATION. It hurts sooo damn bad and I have no idea why, it makes sex no longer enjoyable for me 😩 I have no idea what the problem is and I keep getting told that everything is GREAT with my lady parts. I’m sure it’s my cervix that he’s hitting but my god it’s painful. 😩😩😩

Are there any tips or tricks that can make the sex a little more pleasure for the both of us, I’m running out of options and am so tired of being in pain.

Thanks in advance!
