If your guy has roommates, you know they know you were in there having sex with him that first time, because you were still there in the morning. You know that they were talking about it after you left. I hate all of that. When I had been with my guy for a while, but we still didn’t live together, I love being able to say to his roommates, “We are going to have sex. Don’t bother us.” I was taking control of the conversation around it.
