It's very hard to transmit HIV via vaginal sex. Meaning while it was certainly possible he could have gotten it while fukking trains of women, there are more likely ways he could have gotten it. Specifically IV drug use or sex with other men. Assuming Eazy wasn't fukking men, the obvious answer is drugs. Which we know were heavily a part of the party scene of the time.
Just as it would be hard for him to get it via sex, it would be hard for him to give it to a woman via sex. This is basic stuff. No excuse for people to be ignorant about this shyt in 2023.
