So Monday two weeks ago, I had sex with a guy. He said that he had no STD's and was healthy. During foreplay, he fingered me and got me ready. Then he started putting the condom on, realized it was backward, flipped it, and then put it on. After this, he put lube on it, jerked off for a couple seconds, I got ready, and then he entered me. We had sex for a minute or two.
