Is it normal that my cousin did this?

When I was that age, the neighborhood kids, all about the same age played house. of course not every single one....anyway. we copied what we saw, not really knowing what we were really doing. Most of the kids had been molested, which they were made to think was a fun game so they played that game with their friends. when I moved to the country area with my family, I played the same game with my female cousins, same age range, not really knowing. We were caught punished and taught.

I understand you don't want her to be in trouble but she needs to be taught the reality of what she did. idk your age but if she still look at you and your sis in that way, it seems she's still in that younger mindset. Usually happens when a child has been molested or was in a dysfunctional home. As she gets older she's gonna still go to the ones she trust you two because you have that secret, and if she has les tendencies or curiosities, she'll probably want the advice and/or practice. You need to have a serious talk with her

Your cousin sounds like a creepy person. Lesbian tendencies or not ya'll are cousins. Although I do suspect she was probably molested. This may sound mean by some people's standards but tell her you and your sister don't like touchy feely stuff and if she keeps it up just don't hang around her or more importantly don't let your sister hang around her. If you feel you can tell trust them tell your folks about what she did when ya'll were little kids. As far as I'm concerned it's not really snitching if the person is a pervert with incestuous tendencies. Whatever you do don't worry about hurting your cousin's feelings!

I'd say it was an indication of natural attraction to the same sex. I don't see anything wrong with it either, as it was not hurtful, but a genuine expression of affection. Sounds rather silly to tell someone to stay away from your sister when what happened when when everyone was like 4 or 5 yrs old. LOL

Kissing cousins.

Its not normal Because she is your cousin. if she want not then It wolud be fine as long as you were cool with it. And keep your sis away as much as you can from her I know its hard Because your all family but its for the better its for her safty. and talk to your mum or dad or someone about this. Take care :)

I remember when I worked in a children's camp they spoke to us about "how kids normally explore" they either copy what they saw on tv, or they are curious about other peoples bodies as well as their own and that's why they do what they do. They aren't aware that it was wrong, but if the situation happened we were taught to report it and explain that that behavior is not tolerated.
Talk to her, tell her that you don't like it if she is still doing it. If she continues after that, then you may have to tall an adult you trust (perhaps your parents) or someone of authority.
