I live in a sexless relationship for several reasons. One - I'm on Venlaflaxine for anxiety, panics etc. It has the opposite effect of Viagra.
Two - I just don't fancy my wife any more.
It doesn't stop me wanting sex and I certainly think about it if I see a pretty lady but I just don't think that I have the ability any more.

Sex is kind of a subset of love, isn't it? Isn't to love a general verb for relationship-consistent activity that would be consistent with the emotion of love?

Live alone.

So many other factors involved. If I was in love I'd not philander say in the case of medical condition, and if I did would be very careful not to hurt my loved one and certainly wouldn't allow myself to develop feelings for my "outlet".
However, if the situation is where the scales tipped too far into the negative the clock begins to tick and circumstances would leave me vulnerable to outside influence.
Another lifetime ago I would not reserve monogamy for men who would not do what was necessary to keep me, with the exception of one bf & my late dh I kept seeing other people.
/was loyal to a fault w/dh , it was as if other men ceased to exist

If you have to ask... It is time you move on.

Personally sex is not the most important thing we spend way more time in a relationship doing dishes than boinking ea other so if we were still in love sexless all the way

The answer all depends on where sex falls on your hierarchy of values.

This can only be answered on a case by case basis.

No way to answer that. Everyone is different.
What works for one, will not work for all.

Depends on a lot of factors but mostly why the relationship is sexless: is it a medical condition, are the partners no longer physically attracted to each other, or is one interested in someone else instead? There is no blanket answer to this question.

That is as subjective an issue as it can be. Everyone in that situation needs to answer it for themselves, and everyone will have a different calculus.

This is a hard question! I am not in that situation, nor have I ever been there! But, love is more life supporting than sex...so i could live in a sexless relationship! I am in control of my sensual nature...it does not control me! But, never would I speak for another...
