It really depends on which kind of crossdressing for me. I LOVE a feminine body, so those videos with a twink in brightly colored girlish clothing always get me going
been cross dressing and cosplay for years, the best advice I can give is u need a lot of time to prepare, the things that people often forget is to maintain your mannerisms as opposite gender. The hard part is cross from male to female,cuz people can easily notice if your mannerisms as female is off even just a little. and your make up must be perfect, well u can always ask your friends for help or hire a makeup artist to perfect your looks.
