I would like to apologize for this post to begin with but I am very embarrased and concerned about my son's recent behavior. I have, on many occassion, found him pumping his private area against his stuffed animals, the stairs, and many other things. He has not, to my knowledge, seen such behavior on television or anything. I am concerned because the man that he considers to be his father had a very deep bond with him that I could never understand. Is this usually sexually explicit behavior normal in toddlers or do I have a reason to worry about my son's past with this man (who, by the way, I no longer let see my son as he recently threatened my life). Thank you for any help that you may provide.
