i may have prosopagnosia and a plethora of other sensory human recognition insensitivities (eg not able to tell a persons age within 10 years of their actual age after the age of 15), but i can always sense who is genetically female and who is not.
there is some show i watched a few times recently called "pretty boys" (on cable TV whilst going to sleep and not bothering to find the remote control to select a better channel), and it purports to show the most "convincing" sex changed men, and it also shows their partners who generally come from western countries, and who are completely satisfied with the sex changed men even though they (the partners) were avowedly heterosexual "back home".
some of these partners are rough looking bikie men who claim they like a "good busty woman", and they are not phased in the slightest at the fact that their current partners (the sex changed men) are fundamentally male.
i can always see how sex changed men are not authentically female for many reasons.
they have a harshness about them. their faces are more angular and their jawbones are hard and jutting. even the most feminine looking male face is not feminine in the way of a classical generic female face.
they have a gloss to their skin which seems to show the added effort they have to undergo to make their skin look smooth like a female who does not have to work hard at it.
one can see that the hair that they would otherwise have on their legs (if they did not pluck it or shave it or hormone therapy it away) is of the same distribution that is characteristic of a male.
their adam's apples are always somewhat present.
they have bigger bones, and less soft fatty tissue covering them. it is especially noticeable in the wrists and hands and shoulder blades and knees and ankles and feet and brow ridges (and mandibles and maxillae etc etc).
the way they walk is also revealing of their maledom. even if they ponce around, they still look awkward and heavy footed compared to females. their hip to waist ratio precludes their ability to gyrate in a feminine way.
in real life, i can always smell a male and i do not like the smell. females either have no smell or a more homely smell to them. male B.O. is acrid and confronting and is quite aggressively animalistic and "in your face". like an animal enclosure on a farm. sort of uriney and nitrogenous (vaguely like an ammonia and yeast combination).
i have never smelled a female who had B.O (except for one but that is another matter).
i am sure that transsexual people are just as valid as anyone else on the earth and they deserve to live with the same opportunities as everyone else. i have no derogatory or derisive opinion about them.
i have been called homophobic and anachronistic many times because i am not able to be seduced into the mindset of eager people trying to sell me a line. whether they like it or not, there is no accounting for taste, and i am unmoved by their glowing endorsement of something i find unsavory.
