I believe that just about every gay man has a period in which he is quite promiscuous, usually soon after he comes out or acknowledges that he is gay. The sexual social development of gay men, especially older ones, is not similar to that of straight men. For example, we get didn't know what it meant to have a high school boyfriend, except on the sly. We couldn't hold hands or kiss in public, attend the prom together, or go through the painful experience of breaking up ( which could ultimately lead to a better adjusted relationship). We often lived in fear that anyone would discover our " secret," especially our parents, or even hint that we were " different." In some places, being gay would make the boy or man fear for his life. Many were forced to date girls and some to eventually marry. So, for many gay men, once the proverbial floodgates were opened, we made up for the years of repressed desire and went through a promiscuous period. Some stayed there, others found partners. But, I would agree that, in general, gays can be looked at as being more promiscuous. After all, in a bathhouse or on Grindr, you don't have to buy dinner in order to get laid.
