The New York Times published a brillant essay from gynecologist Jen Gunter about sexless relationships and the implicit understanding that it's often the woman's fault.
"Our society seems almost built on the erroneous idea that all men want sex all the time, so I imagine it would be hard for men to admit to a lower libido, even anonymously. I have lied about my weight on many forms. That doesn’t make me a broken person; it just proves that a cloak of invisibility doesn’t hide you from yourself. The most damaging lies are the ones we tell ourselves."
Relationship problems rarely get better on their own. Addressing sexual incompatibility in your relationship with a trusted therapist can be helpful in moving forward.
