Hi everyone First let me say thanx for all the honest answers in this forum.I have kind of a strange question I hope someone can answer. I am a parapligic but can still get an erection and have fealing in my lower body although it is dimminished slightly anyway I cannot or at least have not came but 1 time in the last 10 years I have heard that electronicly a person can be stimmulated to cum. Is this true?and what about anal sex will that help?Thanx for the time Outback
