I'm a female and have been struggling with this issue for about three years now. Every time I masturbate at night, I wake up the next morning with really intense stomach pain that lasts for around four days. During those days, the pain is so bad that I can't even eat because it makes the pain worse. I've noticed this only happens after I masturbate; otherwise, I'm totally normal. I've gone to several gynecologists, but none have been able to help. I'm really desperate to find a solution to this. What could be causing these severe stomach pains after masturbation, and how can I get relief?
