I recently performed fellatio on another man, within the past few weeks. I'm also in what is a monogamous relationship with another man, who performed fellatio on me a couple days ago. I know I screwed up, but now I'm worried.
This morning I work up with pain at the tip of my penis, it almost feels like its cold. There is no discharge of any type, and I went and bought an OTC UTI test, and that came back negative.
Is there any risk I could have anything? Even if I contracted something in my throat, what are the chances it would cause pain on my penis? Or am I being overly paranoid?
