I can empathize with Eric and others. Had to have major surgery some years back for cancer and part of the intestine and my prostate removed. When I recovered somewhat, my spouse and I had a quiet discussion one evening in bed about how well I could continue to do. I admitted that ED was ongoing, but also took the time to tell her of the several times in the hospital when one of the nurses gave me an enema. While it didn't create a raging erection, it did bring on a smaller one and all the usual feelings. Didn't make a big deal out of it at the time.
A couple of days later, we were going up to bed and she excused herself to go to the bathroom across the hall. i undressed and got into bed. She walked in a short time later with a short, filmy nightie and the enema bag in her hand – full to the brim.
“Turn over,” she sad, “It's time for you enema, hot, and soapy.” I turned over quickly, and she reached over to the bedside stand the lubricant, dropped the bag and hose on the bed, and gave me a thorough prostate-type exam. Then came the tube. She held the bag high and in went the soapy water. I was literally in ecstasy, and could feel my dick start to grow a bit. Hearing the gurgling as the bag emptied., I ran to the bathroom after she took out the tube.
A few minutes later, I was back in bed. She reached over and grabbed my dick, saying, “Well, did that enema help?” It rose about half-way in answer.
Since that night, we have had great sex, perhaps not as often, but i get my fantasies, the enema, sometimes giving her an enema, and simply having great, emotional sex. No little blue pills, just the bag, hose, and water.
Don't give up, find alternate stimulation.
