I'm worried about Brian

We went to rent a movie from the Red Box for the kids. Brian pointed to the new Little Mermaid movie and said he wanted to watch girls in swimsuits. Yesterday we saw the BSU cheerleaders dance and cheer. When they were done CJ instantly was right there chatting with the girls. I asked Brian if he wanted to go talk to the dancing girls, he said no, just dance. He tried to call his pregnant aunt Toot and ask her out on a date. He picked up my phone and said "Hi Toot. Want some alphabet soup and watch some TV?" Now today he laughs every time CJ says "boob". I'm concerned for my very perverted son. He is only 2 years old. Isn't this a little young to be looking at girls like that?
