What percentage (%) of a "good marriage" do sexual relations play?

To me sexual intimacy is just as important as emotional intimacy. When we don't have sex for long periods of time, we start to get frustrated. Of course "long period" has depended on where we were in our relationship. When we did long distance it was normal to go 6 weeks or more without sex. Now that we live together, if we're not having sex at least once every two weeks i start getting concerned.

Is sex the be all end all? Absolutely not. But it's still important to us. It strengthens our already strong bond and releases endorphins that make us closer.

I do understand that there are periods in life where we'll have less sex. Children, medical issues, age all plays a factor. We have a strong foundation of trust, love, humor and understanding that keeps us together. But to say sex has no bearing on our relationship is untrue. Sex is a barometer for how good our relationship is.

No sex, bad sex... either of those without good reason and over a long period of time would negatively affect us.

If I had to put a percentage on it I'd say 30%.

I agree with PP as in intimacy in general. Not just physical, but also emotional. For us, it's important but more for FH than me. He needs more physical attention where as I need more emotional intimacy. As long as your relationship has the proper balance and you're meeting each other's needs that's what matters. Sex explicitly I would give 25-30%.
