I kissed an HIV positive girl and having safe sex , what are chances of having this infection?

Considering there is NO "safe sex" other than either self gratification or one partner for life, you are a good candidate for HIV.

While kissing may not be the source of the infection, sex is a definite. Using prophylactics is like trying to fill the grand canyon with pebbles. Pretty useless.

Why you ask? Because vaginal fluid gets on your scrotum, and if you have any open spots like acne, you are susceptible to the infection. They don't tell you this in the "safe sex" campaign because the more infected people there are, the more money the pharmaceutical industry makes. And the more people to experiment on to find a cure. Sad, but true.

No chance from the kiss unless both your lips were bleeding
If you used a condom very little chance from the sex

Chances are that kissing her did nothing. Having sex is pretty risky even if you were using a condom. As long as none of the condoms broke (even breaks that are microscopic) then you should most likely be fine. You NEED to go to the doctor and get some tests done.

HIV is not transmitted via casual contact or kissing. It can only be passed on through exposure to HIV-infected blood, sexual or rectal fluids, or breast milk.

The most common ways are:

having sex with someone who is hiv positive, in which sexual fluids are passed into the penis, vagina, or anus

Sharing infected needles or syringes when injecting drugs.

The lesser common ways are:
oral sex
unscreened or untreated transfusions of hiv infected blood
an accident in the medical setting, in which the health care worker is exposed to infected blood during surgary or accidental needle injury.
hope i could be of some assistance to you. I want you to know that as long as you practice safe sex, you r ok. kissing wont give you aids, so kiss away.

Kissing cannot transmit HIV.

If you used a condom, and it was used correctly, it was 97% effective at protecting you from the HIV virus.

as/ you know/ safe sex /is 99.9% effective/ congratulations on being responsible/ BUT/ keep in mind /you /have /higher risk/ of contracting/ HIV /because/ she is HIV+

you should be safe. probability under normal conditions above 98%.
if i were you though, i would use the thickest condoms possible and check all organs that come into contact (mouth genitalia and so on) for open wounds (including bleeding gums, acne, and such).
it sounds a bit rude, sorry, but if this girl cares at least a bit for you, she wouldn麓t want you to catch it too.
