Can a couple survive a relationship without having sex?

Yes, because a relationship is about consideration and love for the person you care about. Love is a feeling based on your heart and how you feel, not about physical needs or desires. Love is very different from sex and I tend to think sometimes the line gets blurred, and people get confused with the two.

They could, but sex is so important that I would hope they would find it in themselves to have sex. It's not only important to keep intimacy between the people involved, it's good for our own health. Cancer risk goes up without sex, women age faster without sex, it just makes sense to celebrate the most special thing that a couple can share with each other that they don't share with anyone else.

every other married couple do! seriously though, depends on why they are not having sex and if they are both ok with it. Speaking for myself, I don't think I could go without.

That depends on a number of things, is the couple married? Are they both considered healthy? What's the history of the relationship, meaning was there infidelity? If the couple is married and there aren't any health issues or trust issues as a result of infidelity, I'm uncertain as to why they aren't having sex.

Sex, under the right conditions, is perfectly healthy and a great way to express one's affection for their significant other.

If the couple is not married, and both are considered healthy and dating one another exclusively, it really depends on why they are not having sex. Typically a person will not have sex for religious/moral purposes and has made a vow to not have sex until they have exchanged vows. Some women also have a duration rule, which means no sex until "x" number of days, as that helps to weed out the guys who are only around for sex anyhow.

Whatever the reason, a relationship can survive it if it's for the right reasons. And if it doesn't survive because of those reasons, then it wasn't meant to survive (this taking into consideration that the reasons to not have sex aren't insane of course). Hope this helps!

As long as each partner is OK with the other getting some on the side.

Well, it depends on the circumstances. If you're married and perfectly capable of having sex -yet you're not having sex- then there might be something wrong.

No, Sex helps in connecting emotionally stronger and make a couple more closer.

If the people involved are both relatively young and healthy, NO... I don't think a platonic marriage could be considered a 'couples' relationship, per se... more a relationship of convenience or a symbiotic one.
