Caught in the crossfire of Emma’s unchecked lifestyle, Emilia feels her own world unraveling—her privacy invaded by thin walls and mistaken identities, her peace shattered by the echoes of nights she never chose. The relentless confusion and unwanted attention blur the lines between them, leaving Emilia to grapple with the weight of a sister’s choices that now threaten to define her own life.

I (20F) have an identical twin sister (“Emma”). We live together in an apartment while away from home for college. We’ve always been very similar, not just in appearance, but also in the things we enjoy (as stereotypical with twins I guess).
Except for when it comes to relationships.
I’m not interested in relationships at all, not emotional nor physical. Emma is the complete opposite. Ever since we started living here, she’s been bringing another random guy or girl (or both) home like every other night.
It makes me extremely uncomfortable, but since it’s her own life I don’t think I really have any right to judge.
Problem is that it’s really beginning to affect my own life. Not only do I have to listen to her going at it every time (we have *very* thin walls). But since we look practically the same and even our names are similar (if her name is “Emma”, my name would be “Emilia”), I’m getting attention intended for her as well.
She has a reputation with how easy she is to sleep with, and people are approaching me thinking I’m her.
My messages on social media are being filled with all kinds of obscene language and nude photos. When I reply saying I’m going to report them, they get confused because of the “good time we had last night”.
Any time I meet someone new, they only seem to be talking to me because they think I’m my sister and want to have some nighttime fun. As a result, I don’t have any friends.
I got really fed up with it yesterday and told my sister the way she acts is ruining my life. I told her she either needs to change her lifestyle, somehow make sure whoever she sleeps with won’t bother me and make it clear to everyone that we’re not the same.
In response, she told me I need to mind my own business, that I shouldn’t be such a prude and that I could probably use, in her words, “some dicking” myself. It kind of escalated from there resulting me in calling her a sl*t (which is definitely an AH thing to say, but I lost my cool).
Anyway, AITA for demanding my sister to change her way of living, or otherwise make sure her interaction with people doesn’t affect me?
Conclusion
The original poster (OP) is experiencing significant distress because her twin sister’s active dating life is causing severe privacy violations and identity confusion for the OP. The central conflict lies between the OP’s reasonable need for personal space and safety, and the sister’s insistence on her personal freedom, leading to a hostile confrontation.
Was the OP justified in demanding her sister change her behavior to protect the OP’s well-being, or did she cross a boundary by attempting to dictate her sister’s lifestyle choices? How should the sisters balance individual autonomy with shared living responsibilities?
Here’s how people reacted:
As others have said, change your appearance. Different haircut, different hair color, find a pair of funky glasses with plain glass or a very light tint that you can wear even at night, a distinctive and visible tattoo. Anything to distinguish you from your twin.
Get some pepper spray, or even a small can of aerosol hairspray. Put it on your keyring or always carry it in your pocket. Have it under your pillow when you go to bed. Look into self defense classes (good idea anyway).
Social media to private or use a different name.
As soon as you possibly can, move out and do not tell her your new address. She isn’t willing to do anything to be sure her hook-ups aren’t confusing the two of you. It may be unlikely, but it IS possible she is doing so on purpose.
Good luck & stay safe!
To be honest i don’t see how OP is TA for asking, it’s not like she’s forcing her sister to do anything, she’s simply asking her to switch up her lifestyle or differentiate between the two of them because her sister’s lifestyle is interfering with her life and is ending up with her getting set nudes and weird DMs.
There’s nothing wrong with that, i feel like some ppl saying YTA or that ESH are hung up on the fact she asked, which isn’t anything inherently wrong as she literally offered a fair alternative, and her sister straight up declined both telling her to “Mind her business” even tho at that point it is her business because it directly affects her.
OP i’d suggest dying your hair or getting it cut a certain way to further differentiate yourself from your sister, because it’s insanely sketchy to me that she doesn’t try to make it clear that the two of you are different people.
I don’t think that either of you has to change her ways; what you have to do is find new roommates.
There is nothing wrong with the way either of you wants to live; it’s a personal decision. What’s wrong is that each of you wants the other to adopt something far closer to her own way of life. Which isn’t going to happen.
As others have mentioned, you can easily dye your own hair or change its style, which will almost immediately stop people confusing you IRL.
Secondly, you can make your social media private. There are settings to prevent strangers from DMing you. Don’t accept messages or friend requests from people you don’t know. You have no obligation to receive, look at, or reply to strangers.
Changing hair color and lenght, changing social medias handles and putting them on private. People won’t thank it’s you irl if your appearance is diferent and they won’t find you if you have a fake name or are invisible on sm.
Ho , also, move out. It’s only a matter of time before one of her partners tries hitting on you or coles when she is not there and thinks you are her pretending not to know them.

Once or twice could be just a random hookup getting the name wrong, but constantly? Even if the your names are similar that stikes me as unlikely and I’d be worried she’s using your name instead of hers to avoid any blowback that might come from the reputation she is developing.

in all seriousness. i would move out. peaceful sleep is worth every pennies. make some friends and see if you can get a roommates together (no guys) and rent a large unit
I guess she may then learn a lesson when it starts to feed back to her.
OR..
Move out, move away, you’re not living compatible lifestyles, hers in theory, could get you in trouble
If I were you, I would change my hair color and adapt my name on social media. You look the same – and you could try to change this so people notice you are 2 different persons.
Your sister should tell her friends about her twin sister.
And in longterm in could make sense to live in different cities so both of you can have your own lives.
You can’t control her, but you can control your hairstyle.
If you catch yourself saying something like, “Well, I shouldn’t have to change ______ just because she ______,” just realize that you’re experiencing what she feels when you demand that she changes her lifestyle.
YTA.
As others have suggested a hair cut or dye might help but yeah if she’s sending people your social media that’s not okay
It’s too bad you’re at the same college
Have you tried putting a photo of BOTH of you on your social media for now.
Make it clear that you are twins.
It’s probably also time for a hairstyle change.
You expressed reasonable frustration.
