For the most part, we get photo submissions from girls with an over-the-top sexual appetite. So when we asked teenage Arianna how often she masturbates and she told us only once a month, we were confused. Most of our girls do it more frequently. "I would do it all the time if I wasn't living in my parents' house," she explained. "The walls are so thin!" "I lost my virginity in my bedroom," Arianna told us. "And that was such a pain in the ass. Not the sex! The whole hiding-it-from-mom-and-dad thing was a pain. I was out on a date with my boyfriend and we were having such a great, romantic time, I promised him that I'd sleep with him that night. I said it half-joking, but he still showed up outside my bedroom window around midnight. When it came down to it, I tried to stay quiet, but he was so big and I was so tight, I must have been grunting and stammering more than I thought I was. It was a success, though. It was so romantic."
