Just wondering if you can get like pimples on your penis. Since I had this what looked to be an emerging pimple on my shaft- I popped it and puss came out, just like when you pop one on your face. Is this something I should worry about(as in maybe its not a pimple) or is this kind of thing kind of normal?
Perfectly normal. But as with any pimple, try not to pop them as it can make it spread.
"Believe those who are seeking the truth; doubt those who find it"
These "pimples", like all pimples are clogged pores in your skin. Normally the pores will secrete sebum, a natural moisturizer. Occasionally one will become clogged by the skins cells that your body is constantly shedding and the sebum backs up under the skin. Sometimes the clog will become infected and get red and sore.
Good hygiene and washing with a (rough) cloth will normally keep the clogs from occurring.
Popping the pimple will not cause it to spread but, if you do pop it, use an antibiotic creme to keep any infection from entering the hole in your skin that you have created.
