Okay so I’ve always had sex with my ex and he’d get it from the back and it would never hurt but last month he did it and it felt like he was hitting something and it hurt really bad.. I thought nothing and just figured it was from my period just ending... but today I had sex with my bf and we tried to hit it from behind and it hurt again just like it did that time... what the heck is going on!?! Is there something wrong with me or something that happened because it used to not get and it felt really good but now it’s really painful to do.... please help!
