Penis issue. To more important areas.

One day, out of the blue and all of a sudden it stopped working. I couldnt get erections. I havent had an erection in the morning since it started. I havent had a proper erection that i can keep up for more than a few minutes for sex either. I can still ejaculate fine, and can manage sex (albeit very unfulfilling for both me and my partner) - there is a loss of feeling in my penis also. All i can get is small half-full erections. However, this isnt the main problem. The main problem is that my penis has become constantly withdrawn. Its tight, and constricted and as a result is sometimes painful and often uncomfortable.  Its so tight that it doesnt properly droop down like a normal flaccid penis, and sticks out more at an angle. Its also really thin. - I know this problem occurs after taking certain recreational drugs like amphetamines- as the body diverts blood to more important areas.
