> MTF girls who report having their perineum raphe changing from hormones to becoming more prominent and sensitive
Purest bullshit.
On a male, the perineum is the root of the penis. To duct the urethra from bladder to the penile meatus, the urethra routes through the pelvic outlet (the hole in the bottom of the pelvis that, in females, allows the urethra, vagina and the anus to exit the pelvic cavity), travels up the penile root, then through the penis.
The root attaches to the exterior of the public bone. In males, ofc, the pelvic outlet is much smaller, putting the pubic bone closer to the butthole, so the urethra is longer to allow that extra travel.
The perineum is ofc where the female vulva would be, and you can feel the perineal seam where your proto-vag healed over in the womb. Some of what would have become labia also turn into the scrotal sac.
Helen Gurley Brown's jizzrag used to tell women to stimulate the prostate by rubbing the perineum, which explains a lot about how retarded women are:
Ignorant twat: As a person who might someday breed [God no plz], I should know about the pelvis!
Cunt-Helen: If you want to stimulate a man's "G-spot" prostate, just rub the perineum!
Ignorant twat: Wow, thanks, Cunt-Helen, I didn't know you could stimulate a gland from the outside of the body THROUGH SOLID BONE. Good to know!
Size: if you are on HRT, your perineum will probably shrink along with your dick. If you want a bigger one, click on those penis enlargement ads (probably the least destructive thing you can do).
Sensitivity: HRT makes your skin thinner, and you may end up conditioning yourself to link buttfun and perineal stimulation. But that would be about it.
Color: women's labia get darker as they get older. This is due to leakage of blood from the delicate capillaries (from fucking, from childbirth, from sitting down too hard). If you're pale-skinned (like, redhead pale), you may have noticed some bruises never quite fade. Once the leaked blood is scavenged, some iron from the red blood cells stays behind. This is why dark labia have that particular color: blood red with hematite gray.
