Hello, I am a 20 year old female and I was wondering if you could perhaps answer this. After/during masturbation with a dildo, I sometimes feel this ache/pang in my stomach. It is not my ovaries, and it is not menstrual cramps. If I had to place the pain, it actually feels like its in my stomach. It doesn t happen all the time, just on occasion but it worries me a bit. Help?
