Gender identity and expression are independent of sexual preference! Just like there are macho bi men and butch looking bi women and macho gay men... The mixture of those three elements varies from person to person. Sort of like eye color and sexual preference. As for why some say they desire men while dressed I would then ask how many have acted on that desire and those who did, would you do it again. Some of these feelings may be in the fantasy area.
There have been times when I felt that having a week to dress 24/7 would be fantastic. Then I had a 2 1/2 day stint and found that I just wanted to be my male self again. That showed me the diference between my fantasy version of being dressed versus the reality. The need to get up much earlier so I could get a real smooth shave, moisturize so the extra grooming things, iron my clothes do my makeup. Then a day in heels, clip earrings, girdle and bra...Finally home and then off with the makeup and then start over the next day and do it again. To many here that is heaven, to me it was more than I want. We here are all different. Great Post!!!
