3 weeks ago, I had protected vaginal intercourse with a female CSW, there was no oral performed or received. She briefly massaged me by sitting on my back, when I felt her genitals rubbing against my anus for less than a minute. we changed few positions and after the encounter, the condom did not fail or break. I took shower two times washing my genitals thoroughly with different soaps. I noticed a small tear, as it stung me while I was applying soap near my groin on the crevis where the thigh meets the pubic area. That day I had itching all over my scrotum with redness and burning as if it were on fire in the perianal area which lasted for 2 weeks. During the 3rd week, I noticed a painless sore which looks like an ulcer on the side of my tongue which healed in 2 days leaving behind a white bump less than 2 mm in diameter. I also noticed two to three painless greyish white ulcers 5 - 7 mm in diameter with red lining on the side bottom of the throat, near the uvula which is not going away, 3 - 4 days now. I also think my armpits are also swollen, but they don't hurt and there are no bumps, It could be even fat tissue, I am not too sure. Today is my 23 rd day and I am very stressed out, drinking alcohol to possibly reduce stress. I am not sure If I have an STD. Can you please shed some light?
