>>15957453A crossdresser/CD/sissy is a man who enjoys acting feminine and dressing feminine, almost strictly in private. They usually still consider themselves a man, they just enjoy being feminine for XYZ reasons. (It sexually turns them on, they like the way the clothes feel on their body, they like to get attention from men, etc.")
However, a MTF trans person is someone who no longer considers themselves a man and doesn't dress fem for any specific reason other than they believe in their mind they truly are a female. And they're usually open about it. IT's not just for sexual reasons.
