Does anyone else here use sex to feel okay?

I (34M) have a genetic disability that effects my bone density. I've had over 50 fractures in my life and much of my childhood years were spent in pain, laid up in bed, and in casts. My first fracture was at 17 days old. As an adult, I've found that the only time that I feel truly confident and accepted as well as in touch with my body is when I have sex. I wouldn't say that I'm a sex addict but I have continued to be fwb with my abusive and toxic ex because of how good the sex is. It feels like a tonic for everything I've been through but I'm also miserable and feel stuck in neutral. Can anyone else relate?
