My boyfriend and I have been together for 5 years,  his ex girlfriend was someone I knew in high school and I had a few classes with and she always talk about all the places they had sex ( changing rooms at stores, the prop room for the drama department, in cars, just random places)  I knew they were true as well because everyone knew everyone at my high school. Anywho, I realize that they were super immature and was just super horny all the time but I can't help but to think about it, especially when the craziest place we've ever had sex was in a car. I don't know how to bring it up because he's honestly very embarrassed for ever going out with her and doesn't take to well to her being talked about.
