I'm finding some of the negative comments interesting. I'm get a variety of impressions like:
People think another person's interest in something means they insist on it. Some people, sure, but everyone?
Sexual compatibility means having exactly the same interests. No room for something either is interested but not the other?
People speaking for themselves and their partner. Even if they've told you, the way a person is spoken to can affect their response. If the partner hasn't been asked, that person speaking on their behalf concerns me. Knowing someone else's mind without talking to them isn't normal behaviour.
As for Internet, and delivery of porn through it, affecting behaviour. Every new technology, or the things it enables, changes human behaviour. The effect of easier availability of porn in society, and the controls placed on its availability, isn't down to the porn itself, but the values of the society it was released into. Those values were there before porn, affecting our lives in other ways. Going on memory, the vast majority of the horrid stories about treatment on women here, are the sort that predate the era of easy porn access and its affect on sexual behaviour
