Sex???

So I slipped a disk in my spine the other day 😖 so I’m in a lot of pain at the moment. I’m on very strong pain meds, which I hate, and mostly bed rest. But my so still wants to have sex, which would be extremely painful for me, but he’s mindset on still having sex. I’ve told him I don’t want to and can’t, n he’s just saying that I can go on the bottom and stay still. I’m trying hard to please him but I can’t do this at the moment, not in this state. He’s started threatening to leave me if I don’t do this but I don’t feel comfortable. I’m most likely going to leave him, I just want to know if anyone else has been through something similar? 🙃
