I'm 16 and I've had two maybe 3 pimples on my penis(all at different times). This 3rd is bigger than the others though and it hurts whenever I touch it. I had sex only once and I wore a condum. It doesn't look like any of the pictures of gential herpes, or warts. It looks like a pimple you would get on your face I'm just nervous. Is it something serious?
