the best way to know if you have HIV or not is to get blood testing
how does he know if he has HIV if he has never been tested?
condoms have a 99% chance of blocking HIV transmission.
the 1% chance usually comes from improper use of condoms or if the condom breaks.
you should get yourself blood testing for HIV so you know for sure if you have HIV or not.
there are many HIV or planned parenthood clinics in the UK where you can get blood HIV testing an you will know for sure in a few minutes if you have HIV or not.
using symptoms to tell if you have HIV or not is not a good way to know and is very unreliable.
