Here’s an oddity … people use 🍆 “eggplant” for penis, and 🍑 “peach” for butt, but there doesn’t seem to be a general consensus on which emoji to use for vulva. Some options include:

• Flowers such as 🌷 “tulip” or 🌹 “rose”
• 🐚 “spiral shell”; compare South American Spanish concha
• 🦪 “oyster”; which has a visible pearl (i.e. clitoris) on many systems
• Food items whose names are used as slang for vulva, such as 🍯 “honey pot” or 🌮 “taco”
• 👛 “purse”; compare the origin of the word “pussy” in English
• Any of the various cat emoji, also for “pussy”

(Really there are plenty of other options for penis as well, such as 🌽 “ear of corn” or 🕹 “joystick”, but folks seem to have settled on the eggplant.)
