Hello
Sexual intercourse with CONDOM ( protected sex ).
Shaved area before sexual encounter.
You don't know the HIV status of that female but even with HIV infected ( documented cases ) transmission of HIV infection is ~0.3% in intact skin exposure ( your case come under this category ) and in
mucous membrane it is 0.09%( even if minor abrasion , there is no danger of transmission of HIV infection).
Approximate period of time between initial infection and development of detectable
antibodies is 2 weeks and you got the test and it is NEGATIVE ( PROOF THAT YOU ARE HIV free).
Cough , cold after sexual encounter may be due to flu or
sore throat .
While itching on the chest and neck may be
scabies or louse born infection from that female . Diagnosis can be confirmed by physical examination by a
dermatologist .
Since you are about to go for conclusive test , so please get in it as it will remove your tension.
As you yourself mentioned in the query that you don't have
fever ,
diarrhea etc , main symptoms of HIV ( ACUTE SYNDROME ).
In my opinion you are HIV free.
Hope this will help you.
