Please help me - what is this bump on groin (pics included)

I had unprotected sex exactly a month ago. It is sore and it does not burn when I pee. It never got “blistery” or moist like an ulcer. its actually quite dry/itchy.
I also shaved my bum for the first time about a week ago - if thats relevant.

could be STD/STI or a sore?

ugh yall i have no idea - im going to the drs tmmr but i cant sleep!

did you have rough sex? it looks like friction rub but then it would sting after.
go to the doctors and let us know how you got on

if possible, can you update your post once you find out?
