Oh I was referring to the clitoris (commonly called the bean because the external part looks like a bean) because we are specifically talking about women masturbating. The joke was that I’ve “counted” my own bean, as I am an accountant and made a bean counting joke in a different comment on this meme.

Joke was a bit obscure, I’ll give that, but it is not common practice to call women “beans” – in my repertoire at least.
