STD time before symptoms show up

Hello i would like help with the following situation. I'm a man and i have received oral sex friday, monday i started having unusual pain and a feeling of discomfort. Is it possible that the discomfort and pain im suffering is due to the possible contraction of an STD?? Do STD's symptoms start that quickly? Is that possible or are my symptoms related to something else other than of sexual nature? MY SYMPTOMS Testicle swelling Discomfort PAIN IN THE RECTUM More pee Discomfort while peeing

It could be a number of STD’s or it could be nothing, or maybe even a UTI.. but those are similar to my initial symptoms, and a day later I noticed a sore. I got HSV-1 on my genitals from a partner with the cold sore virus performing oral on me. Yes that is enough time.. Expecially for herpes. You should ask her if shes ever gotten a cold sore before as many people dont know this can be transmitted to the genitals… symptoms typically start 2-4 days after exposure. You should get tested for other STDs to be on the safe side. But be on the watch for any leisions or bumps and if you get them, get them swabbed immediately. Tests for herpes are tricky. They are most accurate during the first few days and after that you could get a false negative. You can get medication to ease the symptoms by visiting a clinic as well!
