Yes the emotional connection is necessary for me too. But I recognize that's it's still separate from sexual arousal. The emotional connection for me is necessary but not sufficient. I love my cat but he doesn't turn me on. People are generally sexually attracted to others long before there is any kind of emotional connection. In fact they would most likely avoid any kind of romantic involvement if there were no chance of being sexually attracted.
If a woman is turned on by symbols of masculinity (like hairy chest, etc.) then it stands to reason she might be turned off when those symbols are obliterated by the things crossdressers do.
The word fetish just means "that which is sexually arousing" when you strip away all the cultural BS that privileges some types of sexual arousal over others.
