Brief Contact of Unprotected Penetration

It's possible. The only way to know if to wait about six weeks and take a test. In the future, always use a condom.

If your penis was touching her vagina (even if you were not fully penetrating her), there is always some chance or pregnancy or STDs.

Even if she did have HIV, there is not a 100% chance that you would get it even if you did fully penetrate her, but there is always some chance when the penis and vagina come into contact, no matter how short a time it might be for.

regarding your exposure you carried very low risk , could you imagine that the full sexual interciurse with HIV +VE person will give about 1 in 1000 to be infected that with out protection. no nnned to worry , you can ask the lady about her situation or you can ask her to test in order to rlife you . or take rapid test in 6 weeks , will be nearly accurate regaring your risk.

Is this your 20th week or day after exposure ?

There are two questions here. 1.) Is the girl infected with HIV? HIV is not some magical divine punishment for sexual contact. It is a pathogen. If the girl is not infected with HIV, it doesn't matter what you do with her, or what symptoms you develop. She cannot infect you. 2.) What kind of contact did you have with her? Mutual masturbation carries no risk of HIV infection. If the head of your penis entered her vagina, however briefly, there could be some risk, however small, because the inside of your urethra could have had contact with her vaginal fluids. This risk would become more or less significant depending on her stage of infection, if she had her period, etc. If you did not penetrate (for example, if the head of your penis brushed her vagina) it is very hard to see how her vaginal fluids could have had contact with your mucous membranes, which is what the pathogen needs to get transmitted. Doing this could give you an anxiety attack, but objectively it is very hard to see how it could get you infected with HIV. So far as I know, up to now, no one has been classified as having become infected through such means. Your external penile skin is not a mucous membrane. If the lady were menstrusting and her external genital organs were covered with blood, this is really the only way I can imagine that such a contact would gain any statistically viable profile as a means of HIV transmission. There are other very nasty STDs you can get through this means. If you already have one of those, it could raise your chances of getting infected with HIV. But the medical books and websites stress that even close, intimate or amorous contact, without exchange of body fluids through anal or vaginal penetration, or by means of oral sex, does not result in transmission of the AIDS virus. Even oral sex is only significantly dangerous for the male if he practices male-female oral intercourse while the woman could have traces of menstrual blood in her vagina. Penetration strikes males as both simple and natural, but by doing it even briefly, you are introducing your penis into the environment of the woman's body, which, from the viewpoint of your health, (and especially hers), changes everything.

I hope this is clear.
