What do you girls think about girls 12/13/14 having sex with multiple boys and posting about it openly on Instagram? I’m 16 so I follow a few of the girls in the years below me and this is all the post about. Personally I think it is disgusting at this age and posting about it saying let’s have round 2 and can’t wait to have sex again etc... what do you girls think?
