Questions: Flirting

So my roommate at first said it was cool that I have my boyfriend over all the time, but now she wants me to text her every time I have someone over. Like every single time. I told her I'm not going to do that and that she doesn't have to warn me if people are here. Like, we live in the dorms. If you don't want to be with other people you can go to the study lounge or something or if you're really tired or something I told her that she could just ask me to GTFO for a while.

Would you expect someone to tell you every time you had someone over? I think she means just my boyfriend, but it isn't like she's walking in on us. I tell her when we need alone time (for sex) but sometimes my boyfriend and I just want to watch a movie (he also lives in the dorms, but he's on the top bunk and the top of the hill so we don't stay in his room as much). I told her he won't be spending the night or anything but she said she doesn't know him so it's awkward. Yeah, that's college. We're roommates, not besties. My boyfriend's roommate has invited his girlfriend to sleep over three times already (we moved in a week ago) on school nights, sleeping on the bed under him. *That* is awkward. I think she needs to deal.

What is your opinion on this? I'm not going to start asking permission to have people over during the day (we live in the dorms, you can just walk into someone's room) but I'm not going to go out of my way to be a d***.

As a note, she is a freshman and this is my second year here.
