If you've been sexually active, you could certainly go do some tests for STDs, but it kind of sounds like this little pimple-looking thing my husband got once on his penis. The doctor shrugged at it, and gave him some medicine in a little tube, and he used it on the bump until it went away. It was truly no big deal.
See your doc, but try not to freak out. :-)
Can someone please help with this? I’m freaking out
