Hiv from sperm on glass?

Question: 

So girl 1 gave me a blowjob and then girl 1 drank from a glass then girl 2 drank from the glass after. Will girl 2 get hiv? what if girl 1 had pre cum in mouth? but she said she didn't feel any pre cum in her mouth.

Answer: 

Hi there and thank you for reaching out to AIDS Vancouver with your questions! We're happy to help.

First of all, receiving oral sex (in this case, a blowjob) is considered to be a negligible risk activity, meaning that while it is theoretically possible to acquire HIV in this scenario, there has never been a confirmed report. Keeping that in mind, HIV is a very delicate virus and cannot survive for long outside of the human body. Once exposed to the oxygen in the air, the virus becomes damaged and is no longer able to transmit. This means that any pre-cum that is present on the glass would already be exposed to the air, and thus would be unable to transmit the virus.

Here is a copy of the AIDS Vancouver transmission to help further your understanding:

BODY FLUID
+
ACTIVITY
+
DIRECT ACCESS TO BLOODSTREAM
• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection

= RISK OF HIV TRANSMISSION

As you can see, all 3 factors are required (body fluid, activity, and direct access to the bloodstream) in order for there to be a risk of transmission.

I hope I was able to answer your question, and feel free to contact us with any further concerns.
