[F27] My ex shared private stuff about me and it excites me

So, I’m a 27-year-old woman who reconnected with a guy I knew from school. Back then, I was dating one of his friends. We hadn’t seen each other in years, and now we ended up hooking up. During our conversation, he told me that he had shared some intimate details about me in the past—stuff like how I moan loudly during sex, give a lot of head but don’t swallow, and stuff like that. turns out it was quiet common that guys shared stories about the girls they were currently dating. I was totally shocked to hear this, since I had no idea he had shared that stuff. At the same time, I felt a bit turned on, knowing that my ex had told others those details about me. It was kind of a wild mix of surprise and arousal to realize how much others knew about me back then.
