I get the dildo part...
But why do they need more then one?

Technically "women buy dildoes" can be a group of women each buying a single dildo, but many do buy more than one.

Why? Because variety is the spice of life.

@dave
Variety means buy a different kind of unhealthy food, not get used to artificial shapes, that will make your pleasure hole desensitized for the rest of your life...

Well... Ok, I guess there is some logic in it.

There's more to it than just size. There's also texture, length, etc.

Also which hole you're using it for matters. Anal you tend to want smaller, etc., oral you tend to want a more flexible material, etc.

You know way too much, and I don't need to learn...
