It's that ". . . and maybe even more . . ." part that is the central truth, here. Doing things that you would normally never allow yourself to do or thinking thoughts you would normally never allow yourself to think - when you are simply wearing different clothing - that's just a fallacy.
You are correct, though. Clothes do indeed have power; the power to allow yourself to admit the truth - a truth that you may never admit when dressed as a male - that you do have feelings (yes, including sexual ones) for the same sex. Truthfully, the clothes don't have the power, you do. Own it, girl! Don't hide behind your clothing as your source of desire. Allow yourself to feel what you want to feel - no matter which side of the closet you get dressed from.
