Today I was at a massage parlor in Asia (yes, dumb decision, I know..), and was receiving a hand job. Without warning, the girl put her lips on the tip of my penis for about 1 second. I immediately told her no, and then she stopped. My penis was covered in quite a bit of oil at the time and I'm pretty sure her lips made contact for a very brief second, but it was dark and I couldn't completely see.
Is there any risk here to get any STD? I am quite paranoid about it right now.
