It can be annoying and embarassing and occurs when the urethra (the tube which carries urine from the bladder to the penis) is not completely emptied.
and the droplets were coming from the penis itself, not like it was sweat or something collecting and dripping (plus he wasn't sweaty). I don't.
The penis has two main functions: to urinate and to ejaculate. Other signs of BPH include dripping after urinating, feeling like the bladder has not completely.
