I would say with this added information that there was definitely something more going on in his life (maybe with the kids in the neighborhood only....but who knows). Don't think it was that innocent though he might not have really understood what was really going on in his whole surrounding life at that age.

I grew up in a neighborhood of all boys.....& remembering back, there was a boy across the street that tried to remove my pants.....he regretted doing that because I fought him....that's what he got for trying to mess around with a tom girl. I never said anything to anyone at the time....but found out later on that there was a lot of sexual abuse going on in his family.....he had 3 older sisters & they were all definitely messed up.

You don't get the interest in porn at an early age if it doesn't come from somewhere & having been introduced to it somewhere. Sounds like he's got a lot of STUFF to sort through & put into proper perspective & make sure where he's REALLY coming from at this point in his life......if the porn has been put in the past along with everything else & your marriage is just between you two, then you really don't have a problem now....but he needs to process the things that went on in his past & set his values appropriately. Just because you have done something in the past, but it's no longer a part or problem in your life....then removing the guilt is a lot easier....but if there are still things following him into the NOW....then there needs to be some work done & you need to know exactly WHAT his values are NOW. Very wise before bringing a child into the picture. Honestly I would rather be safe than sorry when a child is being considered....you have a right to know what his values & thoughts are NOW so that you don't end up constantly on guard once a child becomes part of your family.
