I broke it

Soooo long story short bf and i were having sex , I was on top(only way for me to get off). He complained that it hurt which I’ve heard if you grind in a certain way or too rough you can break your mans penis. Well, I’m positive I did. This happened well over 6months ago. I haven’t been able to ride him since because he refuses to go to a doctor to get a proper diagnosis. I am sooo upset that he refuses to go. I feel like shit because it’s my fault(he constantly denies that) . I was just trying to get mine which if things get better I obviously won’t ride him like that anymore. I just really miss riding him. It’s the same positions every time, I miss pleasing him that way.
