Obvious answer... chocolate. I do not remember when I had a lasting strong erection. I walk fine, for a drunk. I can feel my feet. My prediabetes is very well under control. Viagra is doing its best to kill me, levitra I think it is called sort of work, but those rock ars erections are a thing of the past.
being totally honest, oral still works well even if my mouth is dead, but that is half the fun isn't it?
