Welcome to HCM.
Nearly30-40% of couple, one partner has HIV
, ther other remains negative for HIV in spite of their regular sex contact. They are called as Sero- discordant couple.
So it is not necessarily a single contact with a boken condom to be always infectious.
You can go for either DNA PCR or a P24 antigen test or a COMBO/DUO
test to rule out HIV. These tests are highly reliable and more conclusive after 3-4 weeks.
Kindly change your ideas. Nowadays HIV is a well manageable disease like any other infection and there are millions of people living with HIV comfortably and decently more than 30 years with treatment.
So there is nothing to worry.
Relax and ease youself.
Good luck to you.
