I know you won't go on a vaction, because this has come up before.
On PORN, what is wrong with visiting porn sites, how is it threating you. Do you think H does not have girlie magazines at work. Are you getting any less sex because of it. I don't see the big deal. My LF actually sends me links.
In my case I was facinated at first and still visit it every so often. Once every 6 weeks for a few days, it must be hormones. I can have sex any time(I am not saying with who), but I am not emotionally ready.
Now when I was married, XW became so HD, I actually started to avoid it because it became work. I would not even cuddle, so that she would not think I wanted sex. This just added to her pile, and I was clueless as most guys are.
