Transmission from female to male is virtually impossible. The most common form of transmission is queers getting a dick up their ass.
No, not at all. We had to take a class about this back in the 80's when I was repairing and delivering medical equipment. We had to deliver and pickup equipment from AIDS patients when there was nothing you could do about the disease except die.
When the male ejaculates, the penis gets larger and harder. This causes hairline cracks to form in the penis which is normal. So if that happens in a female (or male) who has AIDS, that's how men pickup the disease. It almost acts like an open wound.
We used to have to dress up in space suit like gear before entering an AIDS home or touching the equipment. Even after spraying it down with all kinds of disinfectant, the equipment had to be quarantined for a week before we could clean it and put it back in service.
It was serious stuff back then.
