I had a fling with a girl about two months ago, I didn't penetrate her, the tip of my penis only touched her vagina opening for about 10seconds,i thereafter ejaculated. Two weeks later I got ill with symptoms such as he ache, flu, swollen neck, and I noticed a kind of tiny round stuff at the back of the tip of my penis, it was inside the flesh and not outside but very tiny and painless. Would love to know what that could be? Could it be an STI?
Did you see a doctor?
It could have been anything - covid, another virus, the flu, etc. Why don't you test and put your mind at ease? It is very, very unlikely that you got any STD from touching the tip of your penis to her vagina for a few seconds, but if testing will help ease your mind, then do that.
