I had anal sex about 8 days ago and a couple days later had this around my rectum. It was my first time doing anal so I’m wondering if this is a cut from irritation or anal herpes? I’ve only been with 1 person for almost 2 years. I’ve googled everything possible. I’m freaking the ■■■■ out. someone please look 
it could be 2 things
- friction during sex
- Genital herpes
get tested just to be safe
from what ive learned on reddit that could be 3 things a yeast infection, herpes or syphillis. do you have any symptoms?
