face to crotch correlation
When a doctor gets so used to seeing ladies and ladyboys that they can spot a fake ladyboy by just looking at their face and crotch. They might even tell you where you're from and how much you've been f***ed.
The doctor looked at my face and crotch and said, 'You're a fake ladyboy. You've been f***ed by a man from Bangkok.'
My friend walked in and the doc said, 'You're a real lady from Chiang Mai. You've never been f***ed by a man.'
I walked in and the doc said, 'You're a ladyboy from Pattaya. You've been f***ed by a thousand men.'
