So, every time my boyfriend and I have sex usually halfway through I start getting sore and swollen. I don't know if this is because I wasn't turned on enough or if we're just being too rough in the bed, but it seems to happen every time. I can usually go through with it but it's kind of uncomfortable for him when I'm suddenly gettin tighter in the middle of sex. It usually goes away within a few hours so I know it's not anything too serious, but it's very annoying. Can anyone explain why this is happening and how to fix it? or if it has happened to them? Thank you so much!
