Re: What would being intimate often do for you?
It would totally change my outlook on myself, her, our marriage, and life itself. I would be more energetic, more productive at work, happier, and more fun to be with. There is NOTHING else that my wife could do for me (alone or in the aggregate) that would in any way, shape or form come close to having the same impact on my satisfaction with our marriage.
Now, many would say that shows a flaw and weakness in my character: that I place so much emphasis on sex. Guilty as charged. And I am sure that my excessive reliance on sex for validation is a big part of the reason my wife does NOT provide frequent enthusiastic sex.
But if you are asking "my husband told me it would have an enormous impact on his confidence, vitality, energy, happiness, and more, but I am suspicious - is that possibly true or is it just a line to get into my pants?" Well, there is no guarantee that it IS true, but it quite possibly could be true. Only one way to find out. If it works and he becomes a better version of himself, win-win for both of you. If it doesn't work and it was just a line to get into your pants, well, I am sure you can think of a suitable form of revenge for his duplicity. If you are even remotely considering doing it, you should. Might as well take his complaint off the table and dare him to make it up to you.
When you can see it coming, duck!
