I’ve known not one faithful homosexual in my life
Not one
I lived in a very gay city, Long Beach, CA, for 15 years, in a neighborhood where lesbians and gay men settle once they are done with the bars and single life. They seemed pretty faithful to me. Often married and with kids. However, most of my gay male friends who are single or casually hooked up do invite others in sometimes. It is a little gay male secret that the couple can go clubbing together.
Having heard their stories I’d bet big on what wardaddy just said. They aren’t using male female courtship as a role model. It’s male libido completely unconstrained because there is no female involved to keep it on the rails.
