Yes, The Tongue Is A Sex Organ (And So Is Your Brain)

When most people talk about sex organs, they're usually thinking about penises and vaginas—two organs often involved in penetrative sexual intercourse, which is the culturally mainstream definition of "sex"—plus, maybe the clitoris and testicles too.

But that's a pretty narrow classification. In reality, any part of the body that triggers sexual pleasure can be considered a sexual organ. Yes, genitalia (the external body parts located in the pelvic region typically used to assign a biological sex at birth) are definitely sex organs, and so are some internal reproductive and body-specific anatomical features like the vaginal canal and the internal part of the clitoris. But importantly, an organ doesn't need to have a reproductive function (see: the clitoris) nor need to be related to traditional sex assignments to count as a sexual organ.

"Any part of your body can be sexual," the Planned Parenthood website explains. "You might have heard that your brain is your most important sex organ. That's because it controls your sexual response—how your body reacts to arousal, sex, or masturbation. It's also where your sexual fantasies and identities are."

According to this more modern and expansive definition, the tongue not only counts as a sex organ, but it's perhaps one of the more underrated sex organs humans have.

You might've heard common wisdom about the tongue being the strongest muscle in the body. While that's not necessarily accurate, the tongue is a pretty remarkable body part: It's, in fact, made up of eight different muscles interlaced together, all of which can perform the same task effectively, thereby allowing the tongue to essentially never tire out. The tongue's all-muscle-no-bone architecture gives it unique flexibility, which can make it particularly good for massaging and stimulating other body parts in an endless variety of specific, rhythmic ways. If you've ever experienced great oral, you know what we're talking about here.
