Condomless intercourse

[Kiwi]

I was wondering how long does hiv stay infectious inside the rectum of a hiv negative person on prep.

So basically the scenario would be.
Person A hiv positive top
person B hiv negative bottom on prep
person C hiv negative top not on prep

If Person A cums inside person B
How long does person B have to wait to have bareback sex with Person C, before person C would have no risk?

Basically how long does the bottom have to wait after being barebacked before it's safe for others to top him bareback? How long does hiv stay viable and able to infect others if it's inside the rectum from a previous encounter assuming the bottom is on prep or didn't get infected?

Is this for real?

C and B are both at risk of acquiring HIV. It doesn't matter if B claims they had condomless intercourse 10 minutes beforehand or 10 years ago; it remains an HIV risk to C.

B claims to be on PrEP, which is nice for them. They could also claim to be a virgin or an alien from outer space, but it means nothing, and even if they tested for HIV today, it means nothing to "C" due to the window period and other factors.

So, I will presume you are "C" in this situation, so it was a potential HIV risk to you. However, for this reason, you take PEP, and if you are on daily PrEP for 20+ days or 2-1-1 PrEP, it's highly effective. With PrEP usage, you should be testing more regularly every three months. I see no reason to test outside of the three-month routine, but do continue to test and consider condoms.

Here's what you need to know to reduce your HIV risks:
Use condoms for anal or vaginal intercourse correctly and consistently, with no exceptions. Continue taking PrEP as an additional layer of protection against HIV

Keep in mind that some sexual practices described as safe in terms of acquiring HIV still pose a risk for other easier-acquired STIs. So please do get tested at least yearly for STIs, including but not limited to HIV, and more frequently if condomless intercourse occurs.

Also, note that it is possible to have an STI and show no signs or symptoms; testing is the only way to know.

Kind regards

I am asking this from the perspective of Person B. There is a reason why i posted this in HIV prevention instead of, am i infected forum.

Therefore Person B is for sure on Prep. And in this hypothetical situation Person C is not on prep and is negative for HIV.

Person A is presumed Positive for HIV, whether he has HIV or not doesn't matter because as you say what they tell you means nothing.

So presuming I am Person B. How long do I need to wait before i have sex with person C. to make sure that Person C who is not on prep is safe?

The question is how long does HIV survive inside the rectum after condomless sex.

This is purely a prevention question. How long does it take for HIV that has  made its way inside the rectum from a previous sexual encounter to no longer be infectious to the next person you have sex with? Presuming you are on prep and did not get infected. Is it hours? Days? Weeks?

This forum only has information on how long HIV stays active outside the body. I have yet to find any information on how long it stays active and infectious when left inside.

So you are person "B."

The question is irrelevant. Person C had an HIV risk, regardless of whether person A had ejaculated inside you or not today or last year; the presumption is and must be that you are already HIV positive for a risk assement, and they should be posting themselves if they have questions. They are old enough to be having sex, and they are also responsible for themselves and their actions/choices.

Person A was also at risk, as your PrEP usage and previous testing mean nothing.

As you are the person "B" in this situation, here is your assessment: you had a potential exposure from both persons A & C, and if you are on daily PrEP for 20+ days or 2-1-1 PrEP, it's highly effective. With PrEP usage, you should be testing more regularly every three months. I see no reason to test outside of the three-month routine, but do continue to test and consider condoms.

How is it irrelevant?
If people can get a direct answer that HIV stays active outside the body for seconds and bottoms are therefore safe from being cross infected by tops not changing condoms between multiple partners.

Why is it that there is no direct answer for the opposite question?

[Jim Allen]

The reason why it's irrelevant and the direct answer is it's an HIV risk to "C" regardless if "A" ejaculated inside you or not before "C" topped you.

bottoms are therefore safe from being cross infected by tops not changing condoms between multiple partners.

Well, I would recommend changing condoms. There are plenty of other infections you could get, not to mention the increased odds of the condom breaking. Ideally, you should change them between positions, but that's unrealistic. But when changing partners, I definitely would change condoms.

Person A has a risk for STIs
person B has a risk for STIs and HIV
person C has a risk for STIs and HIV

If people can get a direct answer that HIV stays active outside the body for seconds and bottoms are therefore safe from being cross infected by tops not changing condoms between multiple partners.

If both tops are using condoms, they would be protected from getting infected. if one of the tops was HIV+, they would not be able to infect other partners because of the condoms. If one of the bottoms was HIV+, HIV would not be spread because of changes in temp and air when the condoms were outside of the bodies.

Why is it that there is no direct answer for the opposite question?

Because it's an unknowable answer. The variables are too varied to determine a direct answer.

Assume Person B was exposed to HIV via unprotected anal sex but was on PrEP.  Unfortunately PrEP is not 100% failsafe and there is a risk of infection. PrEP medication doesn't kill the HIV virus; but it interrupts HIV at various points in it's lifecycle. This means that there is a period of time when HIV will try to start infecting Person B while PrEP (hopefully) inhibits that action. This could be hours to days depending on Person B's immune system, the blood level amount of PrEP, and the amount of virus transmitted during sex, etc.

The only person NOT at risk of HIV in your scenario is Person A because they are already infected. Person B is at risk with condomless sex and or possible PrEP failure. By not using PrEP and condoms, Person A is at risk of HIV.

Unprotected/bareback sex is always a risk..... and that's why Jim said your questions and scenarios are all irrelevant.
