My sister is doing threesome.. Should I tell this to my parents?

She is 23 years old. It is really difficult for a brother to know this. Do I need to tell this situation to my parents to prevent this situation? What do you think I should do?

Superb Opinion

  • A brother should not be involved with his sister's sex life. What's more - parents should not be involved in a person's sex life either. These are adults. Not even that gray-area of adults who are 18, and teenagers - but people in their 20s. What she does in the bedroom consensually with another (or others) is her business.

    A brother should be there if she gets hurt, or be a friend to her when she needs one. Further - this is a fine way to kill your relationship with her. She'd be mortified if you did such a thing - and won't want to talk to you or tell you anything else, ever. I say disapprove all you want, but don't tell others what she's doing privately, sexually. If she wanted your parents to know, she'll go tell them herself.

    • During her experience, I witnessed this involuntarily.

  • You sister is a LEGAL ADULT. It is absolutely NONE OF YOUR BUSINESS, nor your parents' business, what she is doing with her sex life.

    If this is upsetting you this much, you should talk out WHY with a professional counselor.

    I've never had any interest in my brother's sex life: or if he was doing circus tricks in the bedroom with dogs, cats and men.

    I think it's quite disturbing that you think you should control your sister on any level. Please, get some help.

  • I hate to say this but she's an adult now. She makes her own decisions now. If she loves having threesomes then she loves threesomes. You can't do anything about it I know it's hard but you have to accept your sisters wishes. she's 23 now and she's not a little girl anymore. I know it's very hard to process this.

  • Not one damn thing!!! It's her life. She's an adult and it's none of your business.

  • Unless the threesome involves you directly. It's none of your business. Butt out and let your sister live her life for herself.


    If the threesome directly involves you - dude she's your sister, you both need help.

    • During her experience, I witnessed this involuntarily. This made me feel pretty awkward.

    • How did you witness it "involuntarily"?

    • Well Red Arrow gets in there before me. You "involuntarily" witnessed your sis in a three way. So despite your best efforts, your body made you watch your sister have sex with two other people, and you were entirely powerless to go against your body's demands? You're really fucked up if that's the case. Allow me to reiterate. It's none of your business. Telling your family isn't going to make you the golden boy. If your family has a healthy relationship with sex, you're going to get viewed as a bit of a creepy weirdo, and need have your parents sit you down for a discussion about your morals (which it sounds is well overdue). However if your families attitudes to sex are repressed or unhealthy. It's likely to damage your family. Likely to destroy the relationship you have with your sister. Likely to destroy your families relationship with your sister.

  • She is her own person. You should butt out and forget about it

  • No it's not your concern and definitely not your parents.

  • Leave your sister alone! She has her life, go make one for yourself!

  • Mind your business. Maybe u need to experiment more in bed.

  • ... She is 23! Well and truly an adult! She can do what she likes. Maybe talk to her about being discreet about her sex life. The fact that you know about it means she isn’t being discreet enough!

    • Actually she is discreet. She was doing this in my summerhouse. I witnessed this without realizing it.

  • that would be really embarrassing for her if you told your parents so I'd say either let her do what she wants or try and talk her out of it yourself

  • Tell on her, record it and show it to us. I don't have a TV so I never get to see Jerry anymore.

  • WTF? That's none of your business!

  • As for being a big brother I know you want to be her protector & when it comes to her sex life she’s a grown woman & let her do her own thing on this one.

  • Why are you in her business?

  • Ffs. What kind of honor culture are you part of? 1. Stop caring about your sister’s sexlife, it is disgusting that you do. 2. She’s an adult and it is not your parents business.

  • Come on you don't have to be so possessive. Stop being childish. You're old enough and so is she. She can make her own life choices and you don't need to interfere in her matters.

  • Bro, it is her decision. Let her deal with the aftermath and fallout. Furthermore, how do you even know this?

    I find it weird you are interested in your sister's sex life to know this much.

  • It's her personal life... You can talk to her about it if you're worried about her being pressured/forced into it. Otherwise let her enjoy her decisions or learn from them.
    What if it was you?

  • She’s an adult, what she does is none of your business nor is it any of your parents business. Stay out of it.

  • She’s an adult. Why would your parents even want to know? She’s beyond their control.

  • Use it to your advantage. Say I heard about your party of 3. Oh yeah change of subject do you have that friend (sexy girl name here), I was thinking she would be fun to have over. Can you work something out? Yes have her visit before Sun Down.

  • Sure.
    If she wanted it to be a secretshe shouldn't have told you.
    lol, I'd disown my daughter.

  • This would be the time to mind your own business. She is an adult and can make whatever choices she wants. All you would do is stir drama and possibly create issues between you and your sister and maybe even you and your parents.
