Your 3 month test was conclusive. Both because you had no risk in the first place so obviously it would come up negative, and because any HIV test is conclusive 3 months after exposure. Of course you had no exposure because you used a condom, so the test was unnecessary. You don't have HIV.
Is there any risk that you are worried about?
There is no point in wasting time discussing about HIV types and subtypes unless you are a doctor trying to find out some thing specific.
Theres only Hiv 1 & Hiv 2 and no such thing as hiv 3 and 4.
