Thanks for writing in.
The symptoms described by you can be simple FLU
or upper respiratory tract
But also it can be seroconversion
illness of HIV.You have a small but definite risk of HIV with this kind of sexual behavior.
It is better to get an ELISA
for HIV done at this point .Negative test must be confirmed at 3 months .
I advise you to practice safe sex.
Hope this helps.
