Very Low Risk
Oral sex presents a very low risk of HIV transmission. There is an enzyme in saliva that acts as a natural defense to HIV. Having an open and bleeding wound in your mouth does increase the risk of oral HIV transmission slightly, but there would need to be a significant amount of semen containing a high HIV viral load coming into direct contact with the wound.
If you believe you been at risk of HIV we suggest you book a test three months after the event occurred and ensure you use condoms and lube for anal and vaginal sex.
You cannot acquire or pass on HIV by rimming (licking someone's anus). However, oral sex places you at risk for other STIs. We suggest you get an STI test a as soon as you can and discuss your experience and possible HIV risk during this appointment.
Very Low / No Risk
HIV cannot be passed on through skin to skin contact, e.g. from someone's hands or lips touching a penis or vagina.
If you're worried about personal risk, we advise your speak to your primary care provider.
Very Low Risk
Based on your answers, you are at very low risk of contracting HIV as condoms are one of the most effective ways to protect yourself from HIV during sex. If used correctly, the condom acts as a barrier that HIV and other STIs can't pass through.
Some Risk
While not as extreme of a risk as anal sex, vaginal sex without a condom or with a broken condom still poses a risk of passing on HIV from infected semen, pre-cum or vaginal fluids.
We suggest you get an STI test as soon as you can and discuss your experience and possible HIV risk during this appointment.
Very Low / No Risk
When taken as prescribed, PrEP ensures there is enough HIV medication in the body to significantly reduce the risk of becoming infected with HIV if exposed during unprotected sex.
Remember, PrEP only prevents against HIV. As part of your regimen, make sure you're getting tested for STIs regularly. That way, if you do pick up something like syphilis, gonorrhea or chlamydia, you can get it treated quickly and prevent it passing on to anyone else.
Some Risk
Anal sex without a condom or with a broken condom poses a risk of contracting HIV.

PEP
Because the event was less than 72 hours ago you should access PEP– a short course of anti-HIV medication that may be able to prevent you from HIV infection. To access PEP you will need to head to the emergency room as soon as you can – as the longer you wait, the less effective it will be. Click to learn more about PEP. If you don't think you will be able to initiate PEP within 72 hours then change your answer above for more relevant advice.
Condoms
When people become infected with HIV, the virus begins replicating very quickly in their body. What this means is that people who have recently contracted HIV are at the point where they are most infectious they will ever be, and so are most likely to pass the virus on to sexual partners at this time. Therefore, it is vital that you use condoms and lube for anal and vaginal sex if you are unsure of your status. To request free condoms, CLICK HERE.
Why high risk?
Unprotected anal sex (which includes the absence of condoms, PrEP or U=U comes with a very high risk of HIV. Other STIs are also a risk when there's no condom involved. The risk of HIV is slightly higher for the receptive partner, but it's still high if you are topping. During sex, the lining of the rectum of the receptive partner ('bottom') can get damaged and HIV can enter the bloodstream of the insertive partner ('top'), either through the penis hole, or through small cuts on the skin.

Testing
The window period is what we call the time when HIV may be present in your system but not detectable by certain tests. Evidence of HIV can be detected by some tests as early as 2 weeks after exposure, but it may take up to 3 months. Everyone responds differently to the virus. This is why a negative result should always be confirmed by a follow-up test around 12 weeks later. Also, you may want to consider getting an STI test a week or two after this event - we suggest you talk to someone at your appointment about your possible HIV & STI risk.

Sexual activities and their risk.
Different sexual activities hold different amounts of HIV. If you're wanting to find out the risk of sexual event, please use the tool at the top of this page to find out what the risk might be and what your next steps should be.

Masturbation/hand job

Oral sex
Oral sex presents a very low risk of HIV transmission. There is an enzyme in saliva that acts as a natural defence to HIV. Having an open and bleeding wound in your mouth does increase the risk of oral HIV transmission slightly, but there would need to be a significant amount of semen containing a high HIV viral load coming into direct contact with the wound. If the wound was very minor, it's unlikely that this would happen. -
Unprotected vaginal sex
Unprotected vaginal sex (which includes the absence of condoms, PrEP or U=U) while not as extreme of a risk as anal sex, still poses a risk of passing on HIV from infected semen or pre-cum. The virus can be transmitted through the lining of the vagina and absorbed into the bloodstream.
HIV in infected vaginal fluids can still enter a person's body through the tip of the penis, the inner folds of the foreskin, or through small cuts on the skin. -
Unprotected anal sex
Unprotected anal sex (which includes the absence of condoms, PrEP or U=U) comes with a very high risk of HIV. Other STIs are also a risk when there's no condom involved. The risk of HIV is slightly higher for the receptive partner, but it's still high if you are on top.
During sex, the lining of the rectum of the receptive partner ('bottom') can get damaged and HIV can enter the bloodstream of the insertive partner either through the eye of the penis or through small cuts on the skin. -
Other risk factors
Needles: Blood to blood transmission most commonly occurs when a needle is shared between people who inject drug, where one user is HIV positive.
