>You're probably going to be very disappointed with some of these outlooks you have.

That's possible,... But you know, I'm married, have a kid, have been with my wife for more than ten years, and still am very satisfied with the relationship we have, so it's not like I'm without experience.

On the other hand I'm used to seeing long term relationships failing, and often one of the sources of frustration is on the sexual side. It's never the only reason (because things are always more complicated than that), but when this frustration is present (be it cause or consequence), it's not a good omen for the future.

But like I said, there are many different people, and probably both of our experiences just illustrate different walks of like. The most important I find is to know what works for you, and what does not. For me, I find important that I go out with a woman that has a cheerful and demystified approach to sex, but your priorities may differ.
