TMI Question

Okay so last night after me and my boyfriend had sex he said “babe what is that that my dick is hitting it feels like a bone or something” I didn’t really know what to say because I don’t know 🤷🏼‍♀️ A hour or so later we had sex again and I noticed it this time too! He said he’s felt it every time since the first time we had sex which was about a month ago. It’s not painful at all for either of us.

Note this is not the first time I had sex or the first guy I’ve had sex with. & Nobody’s ever said anything before and I didn’t notice it either.

Could something be wrong should I go to the doctors?
