I have phytophotodermatitis, and had an incident which covered most of my body in horrible rashes and blisters. The doctors gave me some sort of steroid and some other medications to counter this. We aren't sure what happened but since then I have lost nearly 40% of feeling over my entire body. I can't feel most of my hands and feet, the entire front of my torso is nearly dead to feeling, extending down the my groin. I am fully capable of getting an erection, but lack feeling on most of the surface area of my penis.
My girlfriend has a very high sex drive and wants to have sex multiple times a day. I am fully capable of satisfying her, but I don't really get much out of it. It feels likes sex is more of a chore than anything nowadays. What little sensation I can feel in my penis is just starting to feel like nothing due to, from what I can guess, over stimulation. Is there anything I can do to increase my sex drive? or even possibly restore some sort of feeling? If not I feel like our relationship might fall apart and I really don't want that to happen. Any feedback would be much appreciated.
