This is a neat one:
Yep we were all ladies once…kinda. All babies will turn out female unless the baby turned male by male hormones. This is why XY people with androgen insensitivity syndrome manifest themselves as more-or-less normal females, and actually have a higher incidence of heterosexuality than traditional XX Females with full hormonal sensitivity. In other words they are genetically male, but due to an insensitivity with male sex hormones they manifest as female because that’s how babies develop.
Also while I’m unaware of the name of this trait, males have what I like to call a “Vestigial Vulva”, which is that “Seam” that runs from the tip of the penis down the underside and across the scrotum. This is where the vaginal opening of the developed fetus closes up.
Pretty, cool, huh?
If anyone can come up with a scientific explanation for the transexual hooker that was working in the motel room next to me last week, I’d appreciate that. He/she was better looking than 90% of the women I’ve ever been with, yet, presumably, had balls. Uncomfortable on many levels.
