My first time was with an upperclassman I had a crush on, three years older than me. It happened at his family home, and while we were having sex, his grandmother walked into the room, which was so embarrassing. Since there was no bleeding, he suspected I wasn't a virgin. In reality, my hymen had torn during a vigorous physical education class. After that, we broke up, and now I'm dating a classmate. We hardly ever have sex, and I feel insecure because he's small down there. But I pretend not to mind.
