Well I've spoken to a handful of men, who all assure me its only normal behaviour if its enabled (so to speak). Yes of course all guys have a fascination with sex, thats normal. But to be openly disrespectful about sex (as it seems this is his line for attention seeking) is not so normal. The occasional looking at porn, sure, Marc had his own stash of dirty mags at that age but the other things well I wouldn't class it as "normal" and neither did they. I have to agree with KL in that the only thing they would get for $30 is a peep show if that! But I'm not sure what worries me more, his behaviour or the fact that his mother is bragging about this. I think your husband's advice is good. I really hope their parents see the damage they are doing before its too late.
