Well, no, not really. If you communicate well with your spouse, there's not much reason to hide much of anything other than presents, before you give them.
For example, I setup a channel this evening on our streaming media box so that my fiancé can view various adult sites on the TV, rather than on the tiny screen of his phone. He likes adult video. (Embarrassingly enough, I don't.) He knows about my girlfriend and what she and I do together. She'll hang out with us sometimes before I go out with her. We're all good friends. It wouldn't bother me if he had a girlfriend - at least as long as he told me about her.
We try to be transparent here.
I know this is a foreign concept, because our society discourages this, but honesty actually does work all the time. It does require a great deal of communication though.
