To me sex is a strong need. I’m in a sexless marriage and get my needs met elsewhere. So this is a bit difficult to answer because in our case we can still make the marriage work but if it wasn’t for my affair partner I couldn’t do it so I’m going to say it’s vital.

I believe its important because it can strengthen a bond and it makes me feel desired. My ex husband and I were very unhappy and I hated doing my duty every month or so. We finally split and 5 years later I fell in love and I'm now feeling respected, loved, cared for and we have a wonderful sex life. I know those feelings mean I have the desire to have sex.
Ex felt more like an unwanted lodger whilst I now feel like a share a home with my new husband.

I feel like we've been asked to do an essay 😂

Or maybe the better question is how important is feeling loved. You can have sex but still not feel loved.

Very important but just as equally important as time, communication and respect

I think it’s important. Definitely not the most important aspect to a marriage but nether the less an important one.
It’s intimacy and feeling loved and taking care of certain human needs. We love having sex and it builds an intimate connection that no one else can replace.

For some it isnt important at all. For others it’s a deal breaker, and for most it’s important for sure. Consensual sex in a healthy relationship is the ultimate expression of love and intimacy.
