Well, it might work for lesbians. However, with gay men it’s just nonsense.
Simply because gay relations are absolutely sexual, gay activists tried extensively to cover-up this fact with influence in media/pop culture to establish a solid ground for their rights.
In major cities like New York, Toronto, Paris or London where there are gay villages, dozens of gay saunas/dark rooms & cruising areas have over come the average gay bars. So, it’s obvious that gay people are not into ordinary dating.
Gay men are not really attracted to each other, There is an over obsession & a thrill in turning in straight men. NO wonder nowadays it’s the fashion in gay culture to accompany an immigrant (Turks, Kurds, Arabs, etc). And it’s a no secret that those relations won’t end up in marriage.
Finally, Gay relations are always short. Simply because both partners get bored and sleep around. Why stay with one partner, when there are dozen of strangers on the sauna next door!
