I was with a masseuse this afternoon and we were discussing a future appointment - I asked here when her period was and she answered it didn't matter when her period was as she worked through and used a sponge.
I couldn't believe it and she said all WG's used sponges so they could work through.
When I got home I googled it and yes there is a video - see below:

She also thought that oral would be OK with lube but she had never experienced oral while with a sponge inserted but perhaps you know different!
