Red spots under foreskin

I hah sex with a girl and all of a sudden I had this red spot under my foreskin. They aren’t itchy or painful I am kinda worry and stressing out. Can someone please tel me what I have I will be going to the doctor this weekend to check myself.

Did you have unprotected sex? Also maybe its just an allergic reaction i had only been with my bf never had any sexual contact with no other guy and he woukd get it turns out mu ph level was irritating his penis so maybe thats what happened

Yes I did but it’s weird cause then they go away and I have to stretch my foreskin to notice them they don’t itch and they don’t hurt
