hey acer, i've been batteling real bad loss of penis sensation for a long time now. over 2 years. not sure exactly how if started.(too tight a cockring for to long? street drugs? neuropathy? too many caverject injections?) sensation seems to improve sometimes, but then my sexual proclivities (cock rings and street drugs, and caverject)seem to bring it back. i'm totally impotenet with out viagra and sometimes that doesnt even work. i've resorted to caverject(u actually inject it in to ur penis, but since loss of sensation i hardly feel it)...anyway, been taking alpha lipoic acid and b-12 (1000 1x day. think i'll got to 5000 as stated above) but its still pretty bad....if anyone has any suggestions as to how to heal this damage, please bring em on. its sad and depressing arrrgh!
