For the last week and a half I have had one singular raised dot on my penis shaft close to the top. It is kinda skin coloured/white-ish and is raised and then round. I really can't find any pictures that look similar to what I have. I noticed it straight after sex with someone I trust, I have had sex with 2 unprotected partners a few months before that.
Please come someone give me a rough idea as to what they think as I'm freaking out that I may have an STI and go through the humility of telling people.
