My H does not see sex as an enjoyable or good thing. He sees it as a physical urge that he has to release and nothing more.
That is a different POV than I am acquainted with. I don't know what to say.
I had the messages that sex was great but here are all the ways it can bite you in the b@lls. Pregnancy, being a pest, imposing on the female, and thought your H might have heard something similar.
I am not wildly HD, don't take many risks, heard too many girls don't like....., but I do have a sex drive that had too many brakes applied for various reasons. I like to call it driving with one foot on the gas and the other foot on the brakes. It waists a lot of energy.
Now BB/W is the one applying the brakes and I apply the gas.
It is god to hear your H is willing to talk about all of this and is having some insights or coming to some answers.
