After urinating, I have a white discharge come out of my penis. Sometimes, after urinating, I feel as if there is more inside, so I push it out. What comes out is a sticky, white substance similar to semen, but I'm not sure if it is. Last night, what came

It. It is most likely prostatic secretion that comes out because of squeezing. You may have congestion of prostate. You should stop squeezing and if it continues after that, you need to see a urologist.
