Yes it is possible, but very unlikely
I got the time wrong, it's about ten and a half years, would it still be as unlikely? Can fathers pass HIV onto their child through the sperm without having infected the mother?
If you are worried about HIV get tested, Guessing will only feed your anxiety. As I said it is very unlikely he has HIV, but possible.
Ok I will, can fathers pass it onto children though without having infected the mother? Just interested
