Hello, Doctor, I seem to have a urological problem. From around 10 days I have problems with the libido. My penis feels numb, and it is difficult for me to get an erection, and even if I do, it goes away very quickly, and there is nothing I can do to restore it. Moreover, today I have noticed that I have many small white bumps beneath the foreskin of my penis. I have read that in most cases these are called penile papules and are harmless, but mine seem to be thick and hard and coupled with the loss of sensation and difficulty of getting and erection, I am a bit worried. I am 20 years old and haven t had sexual contacts recently, so I know that it is not an STD. Can you help me out? Thank you.
