Hello my problem is that after urinating, there is still a drop on the boxer and when i try to wipe it, the tip of my penis stings. mentally can no longer bear this problem. the analyzes are good, except for the presence of red blood cells in the?

Instead of wiping, try to gently dab or pat the drop away. The presence of red blood cells indicates some irritation as does the stinging. Do not rub or wipe, especially at the tip. You might also consider carrying some facial tissue (which is much softer and gentler) with you as this will be much less irritating.

It is quite normal, because the male urethra when the penis is flaccid is pleated, shaking, tapping and gently squeezing the urethra can also be help. There are several possible causes for the tip of the penis to sting after urinating. One common cause is a urinary tract infection. Another potential causes include prostatitis, see a doctor.
