Update. I have carried out a urine chamydia test after 3 days. It is in the post and results will be back within a week.
Also, I have booked a STD doctors appointment for Friday (6 days 8 hours since exposure) to get tested for the standard 4 panel, C and G, Syphilis and HIV.
However, today (5 days), I woke up with dry scrotum so I decided to use to moisturiser around my penis and scrotum. Few hours later, I noticed a one red spot on right hand side of my scrotum, it could be just a inflammed frdyce spot from using the moisturiser or herpes. Hope it is not herpes, I am worried. Surely, if you got herpes, it's normally a collection of herpes spots on the penis head and shaft.
Lastly, still to this day. I do not understand how the condom got stuck in the lady's vagina during sex. I am hoping that I was protected until I pulled out.
Sorry for the confusion, I have not been tested since the condom incident two days ago. The tests I had two weeks was from having unprotected sex with someone else. I am planning a urine chlamydia test at day 3 to send away to the lab via the post.
I am working on the basis that if I do not have any symptoms after 7 days it's unlikey that I have caught herpes (first outbreak 4-7 days) or gonnerhea (95% of men experience discharge with 4 days).
Herpes symptoms generally appear within 3 weeks of exposure. So you shouldn't worry a lot at this point.
I can't explain the Physics behind why condoms get stuck when the male is taking his penis out, but I have read enough online posts on the topic to know that it is not uncommon. As long as condom was intact when you were having sex, and it got stuck only when you were pulling your penis out, you were protected. Your Chlamydia and Gonnorhea tests are conclusive any time more than 4-5 days after the exposure, so you don't need to repeat them. The likelihood of your partner having HIV is very less and even though HIV test 2 weeks after exposure is not conclusive, but it's very encouraging. You don't mention which HIV test you got, so I can't give you a percentage here. But consider this..your exposure it very very low risk (assuming condom was intact during sex), then statistically your partner is very unlikely to have HIV, and your 2 weeks HIV test is negative. Putting all these things together, the chance that you have HIV is vanishingly low. If you would still like to get the assurance of a conclusive test result- current 4th Gen HIV tests are 99% accurate at 4 weeks and conclusive at 6 weeks.
