HIV / STI risk?

[Madvillain]

Hello medhelp,

Haven't posted on here since my college days. But I'm in a bit of a situation. I'm a male.

I have been having protected sex with this girl for about a year and last Sunday we decided to have unprotected sex for the first time. It was unplanned and impromptu, we had sex for about 45 mins at night and again later that night for about 15 mins.

That was Sunday evening. It is now Wednesday and I woke up feeling like trash. I feel really weak, lightheaded, joint pain, coughing, and a significant fever.

Is this something that should be concerning? Prior to our unprotected vaginal intercourse, we have been having unprotected oral sex for the whole year. I've been giving her and she's been giving me.

I'm concerned I contracted something from her, I have slight pain about 2/10 in the tip of my penis in the urethra.

How is my risk for HIV or other STI? Specifically HIV, I plan on getting tested at 3 months. I'm a bit scared because I'm getting sick now.

Extraordinarily low risk.  You can test if you want to, using a 4th generation at 28 days, but it's not a realistic risk.

Your symptoms and timing don't match up with HIV at all.  You probably did catch something - a bad cold or the flu - but almost certainly not HIV.

Thank you for your reply. Can you pls elaborate on "Extraordinary low risk"?

Is this due to the probability of the US population being low for HIV carriers or is this the statistically low probability of infection from female to male via vaginal intercourse? Or both?

[CurfewX]

Both, but even if she's HIV+, the risk from a one-time event is about 0.08%.  That's a 99.92% probability of NOT getting infected.  Multiply that by the chances that she is HIV+, and you're at thousandths of a percentage chance.   Even if you double the odds, because you had sex twice, it's a ridiculously remote possibility.

[Madvillain]

Thank you. If the probability is so low realistically why do people actually contract HIV by intercourse from female to male?

[Madvillain]

Thanks. I'm just trying to understand why I feel like ****. Joints hurt, very lethargic and low energy. The original incident happened one week ago.

Actually, your lethargy claim is the same as the one you posted about in 2014 where they told you to stop checking symptoms too. Nothing new can happen by posting the same question today. This is an hiv forum not a joint forum and most people who are negative but anxious who post here claim that they feel lethargic too - likely it is in their imagination from fear so keep that in mind as a possibility.

If she is negative your risk is zero. Only a test can determine that so you are wasting your time trying to examine your body to calculate odds.

I do plan on getting tested. The exposure was only on Sunday so it's still too early.

Just trying to understand what my risk is. Your comment says assuming she is negative my risk is zero. I wouldn't be worried if I she was.

Assuming she isn't? What is the risk? Are my symptoms related to what you have seen with others who ended up having an issue?

What is the probability of infection if you have unprotected sex with someone who is infected. That is my question.

I already answered that below.  Extraordinarily low.  About 0.08%.
