Normal behaviour?

[mumoffive]

I have an 8 year old step son who masterbates/rocks at night and apparently has done since about 6-9 months old ( He does not get told off or made to feel guilty). He seams very passionate with his kisses and when I first met his father he used to as I called it Sprawl all over his Dad sometimes rubbing himself and then very occasionaly on me it seamed inappropriate to me. He has tried to touch my breasts ( but not for a few months ) and once tried putting his hand between my legs. I thought his behaviour slightly odd when I first met him. He does not socialise with children at school or else where ( other than his siblings) and does very poorly academicaly . He suffers poor concentration and lack of self confidence. He seams very clingy but that has been improving since I met his father and since he has been socialising with my children. There were a few concerens with his inapropriate touching with my Daughter who is 9 but I would have considered it mild behaviour. He is an affectionate and more recently seams happier. His mother died a year ago. She suffered from various problems too many to list but she was not mentaly very stable she suffered chronic pain she was a fairly abusive wife and not a very involved mother. She resented at times having her 2 youngest children. Apparently she was sexualy abused by her adoptive father and had been raped by someone else possibly twice ( she was know to tell lies for attention so who knows) She then sufferd a head injury 2 years prior to her death where her nature became more abusive. My husband does not think she ever abused our son but it has crossed my mind.
Last night we were talking to all the children about smoking and drugs after a news story which then led into a "you should always tell mum and dad if something bad happens to you" which led on to being touched by someone where we dont like it we should always tell an adult... Our son suddenly went very quiet and avoided the conversation.
We asked if he was ok when we had him on his own and he began to cry. He would not talk. He just said he did not like the conversation.
What can we do to help him ? What could be the cause ?  Is this normal ?

Poor Boy, he certainly seems to be displaying signs of Abuse, I would get him a councillor, they are trained to find out and help,excessive Masturbation can be signs of someting that has gone on in his life and it is also a learned behavior, has he any older siblings,in a 6-9 month baby they dont know and sounds like someone has been mishandling him since then, Not a good idea to allow familiar behavior you describe with yourself and Husband, you dont need to push him away just dont get into the situation in the first place. He needs some help so definatly get someone to talk to him.
