Hi - auntiejessi gave you the testing times in her first response to you. So, any tests you take today for gonorrhea, chlamydia, trich and mycoplasma will be valid.
HIV won't be accurate until 28 days post-event, and you need to wait 6 weeks for a conclusive syphilis result.
I'm sorry this happened.
You can test for gonorrhea, chlamydia, trich and mycoplasma now. Make sure to get an oral swab, too. It's not at all likely you'd get anything from giving her oral, but it seems as if you don't remember some things, if I'm understanding correctly, and you could get oral gon/chlamydia if you gave him oral.
You can test for HIV with a 4th generation DUO test at 28 days.
You can test for syphilis at 6 weeks.
You can test for herpes at 6 weeks, and again at 12 weeks, but carefully consider this. The hsv2 IgG blood test has a decent number of false positives, and it takes a long time and a lot of money to sort that out.
Definitely get a physical exam. You could have yeast or bacterial vaginosis causing your pain.
Your username concerns me. Are you blaming yourself? If you were that drunk, you were unable to consent. It's a lot to process, I'm sure. I wasn't there, and I can't define your experience, but if you need help, RAINN.org is a good starting place.
Take care of you, and we're here if you have questions.
