Gay men do not have lower divorce rates than lesbians because men are intrisically better at marriage than women
It's because:
1) Gay men are the most likely to have consensually nonmonogamous marriages - meaning they don't view outside sexual activity as adultery or a breach of trust
2) They are the least likely to bring children into a marriage, and the presence of children drastically increases divorce risk due to parenting stress and the reality that if a spouse becomes a danger to the children, it becomes your moral obligation to get divorced
3) Lesbians tend to get married much faster after meeting than gay men do (hence the joke "What does a lesbian bring on a second date? A U-Haul" which gave birth to the phrase "U-Hauling" in the lesbian community) which also increases divorce risk because rushing into long-term legal commitments bypasses crucial compatibility testing
So no, it's not because men are just better at marriage than women
It's because gay men are statistically more promiscuous, childless, and less likely to view marriage as sacred
I mean gay men have the lowest divorce rate and lesbians have the highest. Two husbands and marriages thrive. Two wives and they fall apart. You sure husbands are the problem?
