Are married men nervous that whatever they say will be quoted on some internet forum, and therefore, they hold their tongue, and not talk.... even though they may be sexually active with their wives ? Some guys think that marriage has to be a private enterprise. Strong emphasis on the private, even though there is less enterprise in it. They don't want what happens within the marriage to get out, to the in-laws, to his parents, to "her" girl-friends, to the internet under assumed names, etc. etc. And that could be the issue when some wives feel that they are not getting the emotional tweaks within the marriage. It takes a bit of work to demonstrate, and establish a reputation with "him", that his secrets are safe with his wife. When that happens, he'd open up and be emotionally supportive.
