Herpes, irritated skin, or overthinking?

i was with somebody about 7-8 months ago and have shown no symptoms of genital herpes in that area and she also said that she was 100% clean. i did get a little bit of back acne and but pimples that felt uncommon but cleared up. I recently noticed a couple (2-3) red spots on my penis that look nothing like blister/. it looks like nothing that the description matches but i am over thinking like crazy and need to hear something back. It has been very humid and i have been sweating a decent amount as well so it could be from that. i have been tested for stds before and those came back negative. I had a blood test done today but am still freaking out.
