I tend to agree. Though it's obvious that gay men will be having more sex than straight men, the level of fetishization and normalization of sexual openness seems to have come from leftist ideology. You'll notice that a lot of married gays tend to lean harder in the direction of normal relationships, rather that "piss drinking at the birthday orgy" levels of degeneracy.

The institution of marriage, due to it's requirement of exclusivity, seems to force gay men to act more sensibly when they voluntarily acquiesce to it.
