Would you consider a 11-12 year old girl who was molested and had sexual relationships with her sisters boyfriend before she even hit puberty rape? I am severely traumatized by it and wish I never ever had sex with him. I feel like the worst sister ever. As an adult who's happily married with kids, I look back at what happen and it makes me sick to my stomach. Why do I have these emotions if I did consent? The guy was over 21 at the time. He's now the father of my nieces and everyday, I worry he will try to do something with them. Am I crazy for having hate towards him? Is this considered rape? I wish like hell I would have said" no" and never had sex with him. 😭😭😭
