I am 28yr old sub. My wife had me fixed when I was 19. I am still able to get hard but she feels I am harder with a condom on. I do however work alot and many nights after keeping house for her, the condom doesn't cut it and despite my willingness multiple sessions is impossible. I surprised her one day with a presciption for levitra and when she was ready she told me to take my pill. We went three times that night and she came more than 4. I went to bed hard, she went to bed happy. Give it a try.
