I've never been out on a "first date". I've always been in a relationship before we started dating, which is weird to say. My first girlfriend, we never dated, but we only lasted a couple weeks anyway. We just hung out at her house. My second girlfriend, we were friends in high school and we kinda gt closer and closer until I asked her to be mine, at which point we hung out like we always did, just with more hand holding and more hugging and eventually kissing. My current girlfriend, we met in college and we hung out a lot between classes until we both realized that we really liked each other and then we just agreed to be together. By the time me and my current girlfriend went on our first date, we had already kissed, and we were already good friends that knew a lot about each other. That was kinda what sealed the deal, though :P

Nothing bad was ever revealed because I already knew the people that I dated. I'm really not one to date blindly, I only ever wanted to date someone I was already good friends with, so I already knew all their embarrassing stories.
