Adams Apple, body hair (facial, arms, hands, chest, legs), tone and depth of voice, lack of breasts or breasts that change size and orientation each day (stuffing a bra), buldge in pants.
Females have longer forearms than men so watch out for these. Males have longer legs and if the thighs seem to be too long then it is definitely a he. Do not get confused, the most sexiest women have slightly shorter thighs than men.
There is the Adam’s apple. It is something that most crossdressers would never hide unless they had it removed through surgery. We all know that females have a smooth throat but if you a big lump on a throat, that’s definitely a man. Some females are so desperate to became 100% woman that they successfully upgrade themselves to such a point where we can no longer distinguish them as male. But one factor still remains for us to judge. Look at the hands. If the hands seem to be big than you think and the veins are sticking out, watch out, that guy is going to get you.
You can also listen to voice which should easily expose them but nowadays crossdressers can sing better than Beyonce and look better. Ahem.Look at the face. Asian women have flat noses while white females have pointy noses. Observe the nose carefully and take a good stare for several minutes, you’ll be able to see through all that plastic surgery without having to strip him/her of his/her clothing. Males tend to have square point faces while females have a perfeclty round face. Although, many Asian men still look like females.In Asia, you can’t tell the different because crossdresser have already mastered the secrets of converting from male to female. The crossdressers in the west still need some work.
