Re: Need advice/help...Marriage and Porn
Here is the bad news: you will never be the only woman he looks at or notices. He is married, not dead. It is normal and healthy for partners to look at other people, humans are hardwired to notice attractiveness. IMHO, it is better to be open and honest with your partner about it, though. My partner will often tell me when he sees another attractive woman (in a very respectful way), and then tell me how pretty I am and how much he loves me. I do the same for him. In this way, we aren't hiding anything from one another. We are open, which builds trust. He doesn't think about them when with me (or he's smart enough not to tell me, which is also fine), and I am the same. We both share our erotica with each other, and are open-minded about it. Hiding it, or forcing your partner to hide it, isn't going to change that they look or fantasize--it's just going to make them sneakier.
The good news is, it's not about you. Just like you might see Brad Pitt and think "wow...what a hottie!" and it doesn't change your desire or love for your husband. Your husband does the same thing. It's part of human nature. It doesn't mean he wants you less, or wants them more. It just means you're not the only attractive woman on the planet. Really, your self-worth should not be attached to this. He loves you, he's chosen you, he's not cheating on you. If he were addicted to porn, or if he were choosing it over you regularly and it was hurting the frequency of sex, it would be a problem. If you feel porn is dirty, that also need to be addressed. But, thinking that any person with a sex drive is never going to look at/notice/fantasize about anyone but yourself is unrealistic and will damage the relationship in the end.
He should be respectful of you, of course, and reinforce his love and attraction for you. You, in turn, need to become more self-confident, and secure in your loving relationship. I am not saying you have to be as open as my partner and I, but it will be helpful to become more realistic about the long term.
"Forever" is a long time not to notice someone else, and his masturbation is not really about you--it's about him. It's his fantasy life, and occasionally he may not want to have to please you, but rather take some time for just please himself. Many, many people use masturbation and fantasy as a release. It is a selfish release, and sometimes that is what is needed (if it is interfering with your sex life, that's different). Even if he's not looking at porn, you can't control what is going on in his head. He may not have the computer screen up or the Playboy open, but he may indeed be thinking about Jenna Jameson or Angelina Jolie (heck, who doesn't fantasize about Angelina--I certainly do!!!). It's not in any way about his love or fidelity to you--it's just a release. Therapists, should you go, are going to tell you the same thing. Fantasy is one of the healthiest ways to deal with and maintain long-term fidelity.
Good luck to you both as you traverse these waters.
