Is that your opinion or do you have a sourse for your statement? In my OPINION, I suspect that porn is not the culprit, but rather the result a spouse who (a) puts on 50 lbs. and looks like a marshmellow; (b) forgot how to have fun; and/or (c) has so many sexual hangups that he or she refuses to have sex unless "it" takes place at night, in the bedroom, under the covers, with the lights out. In contrast, my companion and I are very open about sexual needs, desires, fantasies, and dislikes. We often look at so-called "porn" together and on our own, not the XXX stuff on commercial websites, but the explicit amateur photos that everyday people post to usenet newsgroups. And what we have discovered is that attractive, sexy people come in all sorts of shapes and sizes with various imperfections just like the rest of us. So rather than having "unreal expectations of your wife that will make you very unfullfilled," I see my lady as a beautiful, attractive, highly sexual person whose body is no less perfect than any other average 40 something year old woman.
