He may be a stupid boy who got caught up in the moment but he NEEDS to understand the repercussions of his actions. Hopefully you can talk to him about how terrifying this has been for you and if he's a decent person he will apologize and never do it again.

OP, I take this seriously because my ex-husband did this to me and I got pregnant. He wasn't a stupid boy though. He was a very insecure man who knew the only way a woman like me would stay with him was if I got pregnant and felt I couldn't leave.

Please learn this lesson and do not negotiate with anyone who is ok with putting you through this so that sex can feel better for them. If he can't feel anything it's because he's used to death grip masturbating and that's not your problem.

Stay safe, protect your body and piece of mind.
