What do female sex workers do when they are menstruating?

[pugchops]

My friends and I were watching the box set of 'Band of Gold' when the question arose, do they have to take time off? Offer 'reduced' services or use some kind of sanitary product that I'm not aware of?

Sponges.

Sponges .

Some take time off, some offer limited services, some use sponges, as pp mention.

And some use the Mirena coil, which can stop periods altogether.

Charge a higher price if the customer is into that sort of thing

Run pill packs together so they don’t have a period, sponges.
Don’t forget that some men have a fetish for period sex.
