Every sexually interested soul on earth is interested sexually in people besides their mates.
Also, the connection between "wants the magazine" and "he has me" is more imagined than real. It's not as if people gawk only when they're between sex partners; it's a source of pleasure independent of sex. If he's not compulsive and can do without the mags because you don't like them, then that's about as good an offer as he's in a position to make.
That applies as a larger point, too: The only assurance available to you, or anyone, is that the person you love won't act on outside sexual interests - and that's not an assurance you can simply demand of someone or receive through a commitment or a canceled subscription. That assurance is available in one form only: by choosing someone who shares your belief in monogamy, and who has both integrity and impulse control.
Also know that, in this particular case, you and he differ on values in a way that can be minor or serious, depending on the intensity of each of your beliefs: He has no problem with sexy images and the buzz he gets from them, and you do.
People on both sides of the issue can probably agree that you both have to make peace with the other's beliefs for this relationship to work, because even if he shreds his girlie mags, he'll still be a guy who doesn't think they're wrong to have around.
Question: Would you attend a wedding with no alcohol? Would it matter if the couple were in recovery, versus trying to save money?
Answer: Of course I'd attend, and have. I go for the couple, not the menu or the rationale behind it.
