I used to be mortified when I'd go out. First time was in the middle of the night, I walked to the store and on my way i felt great. AA guy slowed way down as he drove by checking me out, and once i got in the store i realized how bright it was in there, and I was terrified that someone could tell, but i got no reaction.
I get mis-gendered occasionally, sometimes people can tell, just the way it is. But the hotter you look the more people pay attention to you, the more they check you out, the more likely you are to get made for having something extra. Just gotta be confident that you are a hottie and keep working at looking damn good.
Eventually, I stopped caring if people could tell. Although watching a few feminization hypnosis videos on youtube did help. You just gotta let go of that male ego,the male personality, and accept completely that you are a girl, and that being girly makes you happy, and more comfortable. Eventually you will be way more of a girl than you are a guy, and then, the guy will fade out completely. Also, having sex like a girl helps somewhat.
