Okay so a 2 days ago I had protected sex (condom) with my girlfriend. She also performed oral sex and digital sex on me. Now, two days later, I have what seems like a pimple on the base of my penis (where my pubic hair grows). It had a whitehead just like a pimple and also when i squeezed it, it would come out along with some blood. I think I recall having this before, but I really don't remember. Please help!
