HIV is usually spread by bodily fluids from the infected getting into the blood stream of the un-infected. But since you specify women, sexually transmission is much more difficult. Possibly the uninfected woman has an open cut or a bleeding gum in her mouth and is also performing oral sex on the infected woman, possibly while the infected women is having her period. I must caution you though, that transmission through female to female sexual intercourse is exceedingly rare. The most common way to spread HIV from one woman to another is for them to share unsterilized needles, while injecting drugs.
Not if the woman is not infected with HIV.
No; a man can't get HIV from a healthy woman (by healthy I assume you mean HIV free). A woman (or man) can look healthy, but be infected with the virus.
Yes; that is possible.
There is no difference in looks with a woman infected or not with HIV.
Yes, you CAN but it isn't definite
In order to have a baby with HIV, the mother must be HIV positive. When a woman realizes she is pregnant it is important for her to be tested for HIV. If she is HIV+, there are treatments available that can nearly eliminate the risk of her child being infected.
HIV, which cause aids, are passed from person to person by bodily fluids. Females can get infections from both male and females, by sexual intercourse (Both vagainal and anal), oral sex, from blood infected with HIV (for example an open wound splashed with infected blood, or re-using a needle to inject drug, previously used by someone infected) or from breast milk.
No, you will not be infected in that manner.
If there was a break or crack in your skin, then you could catch it.
I guess that there is no possibility of you getting infected by a woman spitting on your penis because HIV in not transmitted by saliva.
HIV-positive means you are infected with the human immunodeficiency virus. HIV-negative means that you are not infected with the HIV.
In order to contract HIV from blood, it must be infected with the virus. Otherwise, you will not contract HIV.
