Hello. Thank you for writing to us
The sexual act that you mention was unprotected therefore risky in terms of transmission of an
STD.
It is not clear to me the kind of sexual contacts that you were engaged in with your previous sexual partner, whether they were heterosexual or homosexual and whether they were protected or not.
The systemic symptoms that you mention in you and your ex- sexual partner are not confirmatory of STD including
HIV but they certainly cannot be ignored without appropriate testing, particularly in the setting of multiple partners and unprotected sexual contact.
I suggest you to get yourself screened for all STD's including HIV.
Screening for HIV is by antibody based test and would detect circulating
antibodies to it if you were infected with HIV, anytime before the preceding 3 months of taking up this test.
I suggest that you visit a venereologist in your region for more details regarding testing and
counselling regarding safe sexual practices.
Regards
