sex is very important in a relationship to keep it alive as such
so why not
if you dont have sex with a partner your relationship is doomed

I think that sex is definitely something that will help in a relationship but it is neither a sufficient or necessary factor for a good relationship. There are so many other factors that are important.

I don't think you have to have the best sex to have a great relationship but you have to be compatible in that department. I am happy with our sex life and I'm happy with us. Honestly I don't know how happy I would be if we didn't have a healthy sex life.

Well if you're all honest.

How many of you would stay with a partner who never wants sex with you?

So of course it's important!

It's always good to spice up a relationship up too, show someone how much you really want and have pure passion for them by just taking them by surprise anytime and anywhere.

And it's always good to try new things and please each other, rather than just please yourself.

I feel good sex is important because it means that the couple have taken the time and care to find out what is really fullfilling to the other. I think it shows honesty with each other. You have to be honest about what makes you happy in sex as well as the relationship. I think it makes your bond stronger if you are on the same path.
I don't think it gauges what a good relationship is about but I think it takes work to have a good sex life with your partner and work to have a good relationship and if you are willing to put in the effort then you reap the rewards of both.
