We have a 17 year old son. In the past two years we have noticed some unacceptable behaviors. He is fun loving, but also addicted to sexual thoughts and actions. He has made advances towards girls underage and unavailable to him. Last fall he exposed himself to a lady, this week he asked two different girls to undress for him. These are things that we have taught as being wrong, but there seems to be a disconnect in his understanding of what we mean or an uncontrol able drive. I am pretty sure he is lying and hiding things. We have two older sons that have not had these problems. While I know that all children are different we are having a hard time knowing how to handle him. Any suggestions would be greatly appreciated.
