Forgive me for being blatantly honest with you but your history does leave a lot to be desired & simply tells me that it is an anxiety
driven scare more than any sexually transmitted disease
However, for an unknown partner & if it still does bother you, objectively speaking, please do the regular STS tests at your local laboratory. Please ensure for best results that for HIV
testing, a PCR test is done as it is early days yet & an ELISA
will be inconclusive at best!
If you feel normal, relax...dont look for symptoms & signs that you may just find if you are so anxious about it. Be objective & do the tests.
In fututre, please remember prevention is better than cure & do practice safe sex
with known or unknown aquaintences especially if it is just casual sex.
Good Luck & Godspeed!
