Hello, I had unprotected sex with a girl two months ago. The intercourse (vaginal penetration) lasted less then 10 seconds, as I came to my senses and pulled out. After a week or so, I spoke to the girl and she assured me there's nothing to worry about. I donated blood a month ago, so if I had any STDs or AIDS, it would show on the tests and they'd call me, that's my logic. Still, I wanted to ask if there's any connection between larger smegma production in the past month and the mentioned case (I have reduced sex activity in the past month compared to normal). Also, is there a valid reason to be worried about anything?
Thanks in advance.
