I met a MtF this past week who had it all done. Long hair, tasteful make up, large breasts, vaginoplasty (it was a clothing optional event - gods save my eyes)...and I clocked that dude from a mile away.
Although I know it to be true, it just reinforced that passing is simply not possible. You can mutilate yourself till the cows come home, and your voice, manly brow ridge, eye shape, shoulders, arms, back, straight waist, hips, mannerisms and leg musculature...it's all man baby. There's no getting around it. Online filters make it possible, but in real life? Please.
I'd also like to add that out of all the MtFs I've had the misfortune of knowing in real life, he was probably one of the closet to 'passing', and still, the end result of that suffering? We can all still tell.
When I read through MtF boards, their claims that 'no one knows the difference' becomes that much more bizarre. Lies lies and damned lies.
