I also notice how "gay" men spend a good amount of time on their grooming/looks while "gay" women let the looks go. I've been informed by a rightie that that's because guys look at the outside, girls look at the inside of a person. So when trying to pick up guys, one must look nice. When trying to pick up girls, one must have nice insides.
... and, when you put the two together, you can achieve an appropriate balance and harmony.
