There are many men that do not have sex with their wives.
The question is why?
Sex very rarely just dwindles out of its own accord, suddenly.
Itamacy and emotional connections are lost through dissagreements that have not been dealt with, or boundaries being crossed by lack of respect or care. (health problems and age can be different)
Women can feel neglected or taken for granted by unthoughtful partners.
Refusing sex can sometimes be a womans last bastion of action before giving up and ending the relationship and the repercusions of that.
Men, instead of apolgising or owning any responsibility for their bad bahaviour will then look outwards for their previlaged rights to have sex.
Here enters the ow, poor lamb he doesn't get any at home.
Therefore reinforcing his right to shag away.
I have never understood ow views about scuppering another womans chances of maintaining a relationship and respecting that those wives need to enforce boundaries within the marriage.
The romance part of it is a lame excuse.
Men don't feel this, they usually just manipulate the ow to get what they need.
To me ow or om are easily manipulated people.
There are so many ow on mumsnet that end up getting hurt by those men that never learnt boundaries and never faced consequences,....and they helped them misbehave!
