I am an 18 year old girl who has been masturbating for many years and I’ve never had a problem. But for the past year or so my o****** haven’t been that great and for the last month I haven’t been able to c** at all. The other day I was trying to get myself off but I couldn’t, so I gave up. But later that day I started to give it another go, determined to get it done because I was desperate to c**. Still nothing. But then I accidentally scratched one of my lips (I have long nails) and the next thing I knew, I was c******. I’ve always enjoyed spanking and stuff like that but I never thought I was really into pain, but I’m beginning to think pain is a big thing for me. That o***** was one of the best I ever remember and I’m a bit scared that pain will become a necessary thing for me to be able to c**.
