I always find the claim hilarious that in relationships women are the ones who need to be appeased, when in reality it's mostly men who can't stand being wrong or corrected.
Gay male marriages remarkably have the lower divorce rates than heterosexual marriages, while lesbian female marriages have higher divorce rates. Multiple studies show that lesbians consistently have far higher divorce rates than gays. This implies a level of neuroticism with females, that they probably do need to be appeased more, and that if you have two needy people who need to be appeased it's probably not going to be a good dynamic.
Interesting. I know that gay men also make considerably more money than gay women, and having more wealth is associated with a lower rate of divorce, which sounds like a plausible explanation to me. I don't know if the numbers check out, though.
