Hello, doctor, I'm 17 years old and since I was little I have a lot of foreskin (phimosis). By the age of 13, I was able to expose my glans out, no pain or no problem, but my glans was sensitive. To end the sensitivity, I began to leave the exposed glans inside the underwear. Okay. It's already gone down a lot. but it happens, that from time to time the foreskin that is retracted, that is around the glans, swells. It does not hurt or anything, but it's weird to see. I would like to know if this is normal and if I need to operate phimosis, since I expose the glans without any problem. Hug.
Expert answer:

If there is an excess of skin and you need to always be doing something to circumvent your anatomical defects is a sign that you need to consult a urologist for him to examine you and decide whether or not there is need for surgery.
