I had intercourse with a woman last night, and this morning (12 hours later) i have red bumps on my pubic area above the penis. Nothing on my penis or testicles. I also have redness on the tip of my tongue that wasn't there previously. I preformed cunnilingus on her, and she gave me oral. A condom was used for the actual intercourse.
Could this be an STI/STD? from what I'm seeing most take a minimum of 24-48 hours to show any signs, and most commonly it is longer than that.
I was thinking it could possibly be irritation from stubble like pubic hair from my partner, as she was on top and i could feel the short hairs poking, the multiple red bumps are on the area that made contact with the stubble like pubic hair. Also the redness on the tongue could just be irritation from friction. All that feels like wishful thinking though.
Is my explanation likely? or is there an STD/STI that shows signs like this in as little as 12 hours?
