I Have A Pimple On My Shaft. I have a somewhat large pimple on the side of my penis that hurts whenever its brushed against. Small pimples on your penile shaft can be caused by genital warts.

Note that I have only. Last night about a year later I got a pimple in the same spot. Its dark red in color.
However sometimes lesions that look like pimples on the penis are not.
Is it a pimple or is it something that I should worry about. There is only one bump but has been there for about a week. In most cases pimples vanish over a period of time or as the person grows. So I have an appointment coming up next month.
