M26, Hi people I have some issues with my penis, I am having a very slow erection, when I am starting to erect I can feel the erection but after certain point I can't erect fully and i manually rub my penis to make it hard, after making it hard and while mastrubating I can't feel any sensation of arousal and when I am about to finish at that point only I can feel anything, in the morning I am getting the morning wood but I can only sense it when I am touching it , is this because of any infection or any damages in the nerve?? Is that treatable ?? I have normal T levels  After one round of masturbating when I am trying to masturbate again I feel some mild pain, I am used to the prone masturbation
