My step son is 5 years old and spends most of his time with his biological mom. We don't agree with a lot of the things she does but I have never though there was anything not good going on. However, a few weeks ago he was watching my hubby play a video game. He said he liked the girl characters boobs and that he wanted to put his wiener on them. More recently he told me that after his dad went to work he wanted me to pull my pants down and sit on his head. I feel like this is not normal for his age and I'm wondering if he is being exposed to something inappropriate at his mom's. Am I wrong? Is this normal for a 5 year old?
