As a bisexual guy, I will throw in a second confirming anecdote.

Theories of sex decreasing because of men being left out of the economy, the secular decrease in testosterone, men being addicted to video games and porn, etc. have to grapple with the likelihood that casual sex hasn't decreased among men-who-have-sex-with-men but rather increased. If that were confirmed, then why are men-who-have-sex-with-women in particular not having sex?

Consider the standards of a gay man and consider the standards of a straight woman. You might find they differ. Also, I tend to find that gay men are more attractive than straight men.

The answer could be that women are just choosing better men in the apps and just becoming the 13th girl in his roster.

Can we stop using verbiage like “better” men? Attractiveness isn’t a linear scale from 1-10, and it’s harmful to perpetuate that myth. It’s multi dimensional and unique to each person.

By "better" I mean some magical quality that makes them better than others.
