As I think back over my rather lengthy life, I don't remember many times at all when I have been complimented on my appearance by a spouse. I have had two spouses spanning approximately 35 years of my life and I am not including Liz in this because she will at the least tell me I look "nice." In fairness, I didn't have the extra benefit of HRT "back in the day." Also, I am the first to admit I didn't look good enough to deserve any kind of a compliment.
Overall though, I have always believed spouses and/or women in general have a difficult time truly complimenting another woman. I'm leaving out the small conversational complements on accessories/ clothes etc. Many times I feel, another woman is just fishing to find out more about me. Or, am I transgender or what. Plus, there is the dreaded "You look good!" not adding out loud...for a man dressed as a woman.
Here is a comment on the subject from Connie:
"However, my wife has never told me that I'm pretty. She'll tell me that I look good in a particular outfit, but almost always after I've fished for it. I know it's because her transition is still a little behind mine, and her memory of the guy she married is not as distant as mine. This is why I say that transition never really ends or comes to some definite conclusion."
Some believe women aren't as competitive as men, which I think is wrong and appearance is one of the top areas of competition. Never believe women don't dress for other women on the same scale as they dress for men. I know when I am going someplace relatively upscale, I consider what the other women will be wearing.
One way or another, the subject gets very complicated. Not unlike gender interaction itself.
