So starting last night, at least that I can remember, I started having an intermittent pain on the tip of my penis. I can cause pain by forcing blood to my penis or kind of squeezing the tip. I've started having a feeling of needing to pee as well. I had sex earlier and it didn't really bother me. It's not a constant pain but it's constantly bothering me if that makes sense. Not a chance it's an STI so that can be ruled out.
