Very concerned for you.

But really, we have over 4 billion women alive right now, and you asked ever. The subwoofer was patented in 1964. Worked up some estimates that there have been 9-10 billion distinct humans alive since 1964, so that’s 4.5-5 billion women.

If none of them ever did what you proposed I’ll eat my hat.

In the American version of Ghosts!, one ghost (Hettie) very much enjoys sitting on the washing machine for this reason.

Absolutely, yes. I dated a girl for years that would orgasm when the wind blew. Not quite, but you get the point

When she was bored she could squeeze her thighs together and make herself cum. She couldn't ride a bike, her eyes would would roll back and she'd almost crash. She would spontaneously orgasm simply from arousal, which was fun because she's orgasm repeatedly while giving blowjobs. She would absolutely orgasm from the vibrations of a large woofer.

"Woman"? Probably. "Human female"? Most likely.

Girls figure out from a much earlier age, on average, that most guys are comfortable knowing, that vibrations in that area feel good. So even without thinking about sex or pursuing orgasm, they will seek out things they can straddle that move in a way that feels good. One of those things, if you're around enough girls or a girl long enough you learn but maybe wish ya didn't.

No I'm not going to duckduckgo that for you

I actually had that happen!!! I had a car with a crazy sound system. I used to sell car audio so I used it as a sales demo. Had a few friends in it showing off. And a girl I had just met went very quiet after she got out out of the back seat. Kinda weird. After they left I get a phone call from the other friend. He's laughing his ass off. She came from the bass and got very self conscious. So ya. My car got lucky... Me... Not so much.

as a woman, i literally thought of this the other day. Given I'm on the low end of sex drive someone else has 1000% done that before

Like in the movie Private Parts?

I feel mildly concerned that I even bothered to attempt to understand what that even means

No. Subwoofers don't have fingers.
