So me and my boyfriend were having sex in the bathroom super uncomfortable. My back was facing him and he was sitting down but there was a certain algo he got to that such made it hurt that I had to flinch and it used to happen alot when ever we started having sex and I thought I had to get used to it but after I started learning we started having amazing sex and it was just yesterday that he hit that angle I just want to know if it's normal or has it happened to any of yall?
