=A simple way to tell if you're simply a cross dresser or truly transgendered=

You can tell that you're really transgendered if after you wipe your mouth & get up from the floor with your tummy full of cum you still want to put on a dress to go about your business for the rest of the day. You don't just feel more comfortable having sex presenting  as a girl,  you feel more comfortable doing everything that way. 

Conversely, if you're a crossdresser, once you've orgasmed, you put on a pair of ratty jeans & a day-old t-shirt & meet your friends at the sports bar. You don't think about dressing as a girl again until the next time you get horny.
