hehe I know how you feel! Dh and I have had many fights over this. We have 2 kids together and when I'm pregnant/just had a child, porn is viewed alot more often. When I started asking him questions about it, "do you like that?" "what do you like?" "would you like to try that?" He stopped watching so often. Apparently it was more of a "omg, I'm gonna get caught" feeling that he liked. :P He'll still throw up a page once in a while when he knows I'm around....if I see it, he'll turn it off and laugh about it. I just give him a hard time about it and he stops it. It's alot better now than it used to be.
btw, my husband and I also met on a dating site. :P
