I think if the LD is occasionally masturbating instead of directing that energy towards their spouse, that is no big deal. If the vast majority of his sexual energy is being directed at his computer, you have problems. The sheer number of websites he has saved would worry me, although I am admittedly waaaaay naive about men and porn.
It sounds like he masturbates VERY frequently and has sex with you once a month or less. That balance would be completely unacceptable to me.
The fact that you've complained about it and he doesn't change would set off alarm bells with me. Does he feel compelled to turn to the porn?
If it were me, I'd keep an eye on it for a while and try to get an idea of how often he mbates and try to determine if there could be a possible addiction. From what I understand this is a difficult thing to overcome and would definitely require professional help.
