I have been sitting a lot for the past 1 yr and it caused perinnial numbness and less sensitivity in penis . On 24th August (4 days before) I masterbated to see if it was allright, and right after ejaculation my penis has shrunk, and perinium was numb. Now on 27th August, perinium feels ok, but penis is still shrunk, and lacks sensitivity. I also am not able to move my penis without touching it, and it feels like there is no blood flow to penis. Urine passes fine, but there is no morning wood, or it is very very very week and goes right after I woke up.
