Hello there,
I found very little about this topic. Today I had protected oral sex, but just for a moment girl did lick/sucked (not sure about sucking to be 100% honest but lets say it happened) my scrotums. It didn't last longer more than 20 - 30 seconds max. No penetrative sex occurred. So my anxiety is here and it strikes really high. Since HPV, Herpes etc. are STI that could be passed by skin-to-skin contact, I just wanted to know what are my chances to acquire some of these STIs. It was a very bad decision that I won't repeat. Please help. Peace and love.
I wouldn't worry at all.
