Asking for his/her name AFTER you had sex

This happened to me once. When in college, we used to have these huge parties that included a lot of drinks and a lot of people. So yeah, it happened once to go upstairs with a guy from my college and we had sex. He left me his phone number, but no name. Two days later I called him and asked for his name. I was kinda ashamed.

Has this ever happened to you?
