I (19M) went to a spa yesterday around 9-10pm, the condom broke midway but she immediately pushed me back within one second, then just took a HJ and went home. I asked her multiple times about her having a STI, she said she's more worried about it than me.
before intercourse we had talked for half an hour like normal people, she even told me about her family etc.
Now that it's been about 18 hours, I'm confused about what to do, there's no burning or irritation while urinating, and my mind says that everything's fine, but I read that symptoms / positive tests may take days or weeks to show up.
Logically, her having a STI is also less probable, and second, there wouldn't be substantial fluid exchange in one second, and third, body's immune system would kill any foreign particle.
I don't want the advice to go to a doctor or get tested, I want to hear your opinions...
