But you're showing a complete lack of understanding of the other side.
The person does not want sex, what do you want them to do? Engage in self flagellation about it? Plenty of people do that and guess what, it doesn't make them horny. They often try to go through with sex they don't want, many end up with a sexual aversion. They often try to have duty sex and are then berated for not being into it and are told time and time again, it's not about the sex, I want you to sexually desire me...But they don't...so what are they supposed to do? Magic up some desire?
They have absolutely no understanding of how sex could be important for their husbands ( or anyone),
The other side often don't understand how sex can be traumatic for the other person.
are actively scornful of anyone thinking sex is important,
Can you think of any reason why that might be? They're often told they're the bad guy or doing something wrong or that there's something wrong with them, from that perspective people will eventually often get defensive.
have no understanding of sex being more than a wank:
But they can't offer the type of sex the other person wants, mutual wanted sex.
no understanding of sex being more than a physical sensation.
They have no idea of sex being more than mechanical and functional.
Because to them it often is a bad physical sensation and it IS mechanical and functional. The person on the other side often doesn't understand how unpleasant it can be.
I would find this attitude a betrayal really, if I were OPs husband. If one spouse makes a sacrifice for another, especially a huge one like foregoing sex, you expect to receive love and appreciation for that sacrifice
So he gets with a partner who always had a low libido and then she's supposed to be extremely grateful that he puts up with her and shower him with love and appreciation for being with her and sacrificing sex?
