Question

Can I get HIV from oral sex?

I’m a male, 30 years old. Yesterday, I had unprotected oral sex with a female who I don’t know her HIV status. I only had oral sex with her. She gave me a blowjob.

I am afraid that if she has HIV, I will be at risk of HIV infection. I’m so worried. Do I need to get HIV test?

Thank you very much!

Answer

Thank you for your question.

You cannot get HIV from oral sex this way. Anyone who is receiving a blowjob is not at risk. You also cannot get HIV from giving a woman oral sex.

Although up to 5% of HIV infections might be giving someone a blowjob, this probably depends on two factors. One is that viral load need to be very high in the positive partner and the second it that the negative partner probably need to have mouth problems, for example if they have bleeding gums, a cut in their mouth or recent dental work.

More information about HIV sexual transmission is included in this guide, which has a section on oral sex.

    Hi Liam, this is not a sign of HIV. This sensation could be caused by a number of things. It is important you speak with your doctor. For more information about HIV transmission please follow this link: https://i-base.info/qa/factsheets/hiv-transmission-and-testing

    Hi Don, a 4th generation test is conclusive from 42 days an onwards.

    4th generation test is conclusive at 45 days or 90 days?

    Hi Subham, oral sex carries little to no risk of HIV transmission. Saliva makes it very difficult for HIV to be transmitted. There has never been a documented case of HIV transmission via oral sex. The symptoms you have are very non-specific and more likely caused by a cold/flu. You can test using a 4th generation test at 4 weeks (95% accurate) and 6 weeks (conclusive).

    Hi, Someone gave me oral sex one month back and I am facing the same symptoms as Jenis.

    Hi Jenish, kissing does not carry any risk for HIV transmission. Oral sex carries very little risk. Saliva has antiviral properties that make HIV transmission very difficult via this route. Have you been to a sexual health clinic/doctor about your symptoms? How long have you been experiencing them?

    Based on this info, PEP would not be given in the UK.
