Thanks for your post.
The main thing is that you used a condom and that that condom remained intact. The sell by date etc does not matter. Provided it was put on, stayed on and did not tear and was then on removal then you will be fine. You are of course making a huge negative assumption that she is HIV positive which in itself, even given her admission that she sleeps with lots of men, is unlikely.
You don't specify the oral sex - were you sucked or did you perform oral sex on her. If you were sucked then there is no risk of HIV. If you performed oral sex on her - assuming the unlikely that she was HIV positive - then there is a faint risk that you might acquire HIV - absolutely faint.
You can use an RNA PCR test from 10 days post exposure, and HIV DUO test from 28 days post exposure and a plain HIV 3rd generation antibody alone test at 6 weeks post exposure.
The symptoms you describe are not HIV.
Kind regards, Sean
Thank you sir for your response ! I'm prolly over reacting . However I started having night sweats now . Could this be due to stress from worrying over this ?
Yes, I think probably an overreaction and yes, anxiety can certainly cause people to wake in a cold sweat.
