I see a double standard that exists.

If breakup/divorce/cheating is a result of the woman refusing sex, that is a problem. "There are more important things than sex in a relationship"

If breakup/divorce/cheating is a result of the man refusing sex, this is not a problem. "She deserves someone that can satisfy her needs"

When the couple is not married, the solution is simple. Break up. But if the couple is married and possibly has kids, it may not be so easy "for the sake of the children". The man will put up with a sexless marriage and focus on keeping the family fed and provided for.

The problem arises when there is temptation to cheat. It's considered immoral for a husband to cheat even if the wife is refusing sex. But, correct me if I'm wrong, it's considered understandable if the wife cheats if the husband doesn't want to sleep with her in the first place.

Even in Antman: Quantumania, a married couple is forced apart for decades in different worlds due to a freak accident, and the woman admitted to sleeping with another man because "I had needs", while the man stayed loyal and faithful. Contrary to what some people claim, this highlights how modern society now tends to accept that women are "entitled" to sex, while men's sexual needs are shamed. (A reversed situation from traditional times, I acknowledge)
