Skin of perineum
Regio perinealis · Kůže hráze
Skin & appendages
Looks like
The skin between the thighs, from the genitals back to the anus.
What it does
Covers the pelvic floor, which holds the organs up and closes the openings.
Keeping it well
Keep it clean and dry; an itch, a sore or a lump that lasts deserves a visit rather than embarrassment.
