Chafing.. or something to worry about?!

So to start off.. i had unprotected vaginal and oral sex 23 days ago and had a UTI that following week and i went on antibiotics and it went away. i now have developed this rash like area as of yesterday around my anus and it is quite dry and raw. i am wondering if this is related to my unprotected sex or if it could be chafing from my new tough denim, high rise, tight, mom jeans i wore for 12 hours straight two days ago..
i also happened to get a mark on my face as well that has just been itchy and tingly.. could be a pimple forming or could it be herpes as well?
does it look like something i should super concerned about - possible herpes?!!

some people often experience tingling or itchiness when they are about to get a sore, you could have herpes and not even know until years later some people may even have symptoms a few weeks after. You should go to the doctor and have it checked out if they say it looks like a rash and not herpes I still suggest you get a swab and blood test for HSV

look just like irritation

u dont get herpes on both the mouth and genitals at the same time whe u get herpes u have it on the mouth or the genitals so its likley that it is not herpes on the genitals if u have it on the mouth and vice versa …the redness looks like its down to wearing the tight jeans and has caused irritation

the only way u would have it in both places wold be if u had both hsv1 and hsv2
