severly

I keep reading into it and the more I read about it the more I feel like I don't have Herpes and it looks nothing like it. But then I will read something that sounds like something I might have and then. Boom! I feel like I have it again.

I'm a 30yo male. So about 5 weeks ago I had unprotected vaginal sex with a woman for about 3 minutes (quick I know). I asked if she had any type of STI and she said she was clean. However I started to get paranoid. 5 days later I went to get checked for chlamydia and gonorrhea, both reported clean. After that I calmed down a bit. About 18 days later I went out for a bicycle ride, which is new to me. I am usually not very active, after my 1 hour bike ride I felt great. 3 Days later I wake up and take a shower, as I am scrubbing I feel pain originating from my penis and when I look down I notice a skin colored lump on the corner of my penis head tip in the area where a penis head splits. Its painful but not fluid filled and looks almost like its irritated. The next day I go to a urgent care center and show them. The doctor lets me know that it does not look like Herpes or any type of STI but rather looks like a yeast infection. Its almost been a week and I still have it, nothing seems to have changed it still looks the same and only feels uncomfortable some days. I have an appointment with my actual doctor coming up but I am freaking out that it might be some type of STI, everywhere I read about Herpes being mistaken for a yeast infection. Some more about me: 30yo, male, hispanic, slightly overweight. Does this sound like Herpes or am I just way over thinking things?
