If I perform fellatio on a person who says that they are HIV negative and were last tested in November, and I didn’t have any cuts or sores in my mouth and I didn’t have precum, blood or semen in my mouth, what is my risk of contracting HIV?

Oral sex is considered low to no risk of HIV transmission. However, this can be different for STIs. We suggest anyone who is sexually active to have regular check-ups with their doctor or local sexual health clinic. If you live in NSW, you can find your nearest sexual health clinic here:

Hi, I recently had an oral sex with a woman that I don’t know her status, so far I’ve had 3 duo combo hiv test one at 14 days, one at 25days and the most recent one at 35days all came negative. But I’ve been getting symptoms like sore throat, dry cough, tired and malaise, inflamed glands around my neck, pain at the back of my neck and head, mild headache, runny and blocked nose and slightly raised cervical lymph gland. I’m really worried, should I take another test in few weeks?

I have had an episode of receiving oral sex from a sexworker 7 weeks back. I have taken Pep in 52 hours for 28 days precisely. I have been reading a lot and have so much different information on insertive fellatio about hiv risk and making me crazy. I can see you have update your original answer from 2010 back in 2018 addressing risk as zero. Can you please confirm if the risk is really zero or just rhetorical? I am due to go for testing next week but really scared

Oral sex is considered extremely low risk for the transmission of HIV and from what you write, it sounds like you have done your research on the topic. Sometimes people can have an overwhelming sense of fear about acquiring HIV, a very treatable condition in 2019, and it can be after incidents they know to be low or no risk. If you feel you are having high levels of stress and anxiety related to acquiring HIV, reach out to a doctor or counsellor to discuss these feelings. You may need to “unpack” your anxiety with a professional to feel as good as you can about your sexual health.

Hello, I'm 25 I got a threesome with two gay guys we only have oral sex and I perform it on both each with different new condom, after that they have penetrative sex between them and I touch the penis of one as it go in and out of his partner, also before they had intercourse they rim each other and in some point they kiss me just the lips. Their HIV is unknown but seems like they probably have it. After two weeks I started to feel soar throat am I at risk?

Hi, There is no chance of acquiring HIV by giving oral sex to two gay men who both have condoms on. The other activities such as fingers and touching also present no risk of acquiring HIV. We would also recommend not assuming anyone’s HIV status. HIV does not have a “look”, a gender, a sexuality, or any other indicator that is identifiable by the eye. If you are concerned about contracting HIV, consider learning about how to take charge of your sexual health by using condoms, PrEP or only having sex with people living with HIV who have a undetectable viral load. These strategies are called “combination prevention”. Learn more here:

hi i have received oral sex for 5 seconds i used condom seconds what is the probability to get infected with hiv ?

Hi, thank you for your question. The risk of HIV transmission through oral sex is considered negligible. Given that you used a condom, which provides a physical barrier, it is very unlikely that you would be at risk of acquiring any sort of sexually transmitted infection (STI). If you weren’t using a condom and partaking in oral sex, you would be at risk of potentially acquiring an STI, such as chlamydia or gonorrhoea, both of which are treatable. If you are sexually active it is important that you regularly get a sexual health check-up. Your local GP can provide this service, or alternatively if you are in NSW you can book a test through or

If u have oral sex and then u have safe sex can u get hiv. I have a sore throat after

Hi, thank you for your question. The chance of acquiring HIV through oral sex is considered negligible. However, it is possible to receive a sexually transmitted infection (STI) from performing oral sex. Most commonly that would be an STI such as gonorrhoea or chlamydia. Often STI’s are asymptomatic (meaning there are no symptoms), so the only way to know if you’ve acquired an STI is to get a sexual health check-up. You can get a sexual health test at a sexual health clinic or your doctor. If you need more information please feel free to call the sexual health info link on 1800 451 624.
