In the gay community, a lot of emphasis is placed on the way you look. I think that gays take care of their body and put some effort into their look daily. Traditionally gay men were usually in better touch with the latest fashion trends hence they looked better.
Gay men are men who are attracted to men, therefore they know what makes a man good-looking. Therefore they can put this into practice and thus you have it why gay men may be incredibly handsome. However that is a very general and simplistic way of looking at it as of course it doesn't apply to all. Some of a persons aesthetic quality is down to how they look after themselves and some also comes down to nature and what you have naturally been bestowed with. One's sexuality doesn't really have any bearing on how beautiful or ugly one is. Some men are beautiful regardless of whether they are gay, bi or straight just as others are average or aesthetically challenged regardless of their sexuality. Different people have different tastes so what one person may think is attractive others may find it unattractive, so beauty is a relative idea.
I can't say all gay men are handsome, that would be a lie.Maybe the vast majority are attractive because they are willing to invest time into staying fit, eating health and being well attired. Being in the gym, on a diet and constantly groomed is just the gay predisposition for the vast majority of homosexual men.
Yes, on the whole, gay men take better care of themselves and pay more attention to their appearance, but there is another reason. It is because the gay men who are older and/or less attractive are invisible. No one pays attention to gay men over 40, or those who are under 40 but less-than-handsome, and this is especially true of gay men themselves. I am now 54, a little bit overweight with gray hair but in very good health. I keep myself clean and dress well, but no one is interested in me. all the gay men my age are looking for a 20-something boytoy and its hard even to have other gay men as friends because no one wants to be seen with someone who didn't step out of the pages of a magazine. They gay world is shallow, conceited and cruel. Once you are over 40, you had better have money or you are socially dead. And a real, serious, monogamous relationship?
