I have virtually no feeling in my dick. Apart from when i blow and the moments leading up to it i get almost no pleasure. I have no idea how i got this way, its pretty much been like this as long as i can remember. When i'm jerking of i have to tense up if i want to get off, otherwise i don't think it would happen. Is there anything i can take or do? Or could i be doing something that could be causing this? Does anyone else have this same problem?
