Welcome to HCM.
You are very fortunate that all your HIV test
There is no chance for you to get HIV through your past sexual encounters.
Relax and forget about the past.
No more test is necessary. If it remains nonreactive even after 6 months then there is no chance for any body to have HIV. All the tests are highly reliable.
So nothing to worry. Stick to safe sex
always when you are away from your wife.
