My new roommate (F 26) and I (F 34) have been living together for 3 weeks. In that time, she's had literally 5 different guys over to spend the night. She usually gives me only about 2-3 hours notice. While I was at work today she texted that she was going to have guy number 6 over--after having a new guy stay just last night-- and I told her we needed to talk.

When I got home, I said that we're both grown and I understood she was dating but I wasn't comfortable with new guys coming over and sleeping over on first dates for safety reasons. It'd be one thing if they had even a couple dates before she invited them back, but by her own admission they talk for a few hours and then she invites them over. When she first moved in she said she was on Tinder just to see "what's out there" but that she'd rarely have guests over given her job (she's a flight attendant) but that hasn't turned out to be the case.

I asked that going forward that she either go to a guy's house or split a hotel room if she wanted to spend the night with them because these men were complete strangers to me and not really known to her. Additionally--and I didn't say this part to her--they're all older white men in their 40s and 50s. She and I are the only Black people on our immediate street (I live in New England) and these men tend to come over in the afternoon and leave the next day. To be honest, I worry what my neighbors might think seeing this. I get it's none of their business--it's not like they pay my mortgage (I bought my house 2 years ago), but even if these men were Black, I'd worry about my safety and what my neighbors might be thinking.

She got upset and said I was slut shaming her. I told her I wasn't but that I didn't think it was a good idea for guys, or even women, to come over after knowing them a few hours. What if one of them didn't want to leave or hurt her or me? I'd feel better if she at least Googled them but she said she follows her gut and if they were "weird" she'd know. The guy ended up coming over but she left with him to spend the night and then she's flying out for a few days for work. On her way out she called me a "overthinking and judgemental boomer". Am I? And did I slut shame her?

Edited to add: Thanks so much to everyone who responded to this post! I want to reply to every comment but I'm working all day so I just wanted to say I really appreciate the support and wise suggestions. When she gets back, I plan on apologizing again if I made feel her judged, but that our safety is important to me so if she doesn't agree with the guest policy, she can give 30 days notice and I won't charge her rent for that month and she'll still get back her security deposit (rent is crazy here so I'm sure this will help her finances). Thanks again, everyone!
