I never said that anyone needed porn; I just said that sexual satisfaction doesn't always fall into place in such a harmonious way that both partners are always as satisfied as they want to be. And your counters to something I'm not arguing still don't address what I am actually arguing. I'm not talking about porn addiction, I'm not even talking about sexual interests or desires, I'm talking about satisfaction.

While I was away, I also remembered something else that Sparkle didn't consider: victims of sexual abuse (rape or otherwise). These people may not be able to satisfy their partners sexually, especially when their relationship with their partner is still young or if the abuse was recent. Abuse can very easily muck up an otherwise perfectly healthy relationship, and is likely to strain both of the people in the relationship.

So again, if you have a partner, that does not automatically mean that you and he/she are both sexually satisfied with only each other, and this satisfaction may very well not be attained "easily." Relationships are too diverse for all of them to be so simply categorized, and there is certainly a place for masturbation and/or pornography (or group sex or any number of sexual fetiishes) in many relationships. But to say that absolutely no one should need any of those things outside of their one and only partner is naive.
