So during WLW sex do you have to stop and clean in between switching toys? How do I disinfect toys in between partners?

Yep! Unless those two humans are fluid bonded and are okay sharing fluids. You can also put a condom on the toy and switch the condom out to avoid having to wash it. If it’s a vaginal toy, you don’t want to disinfect because the antibacterial soap will hurt your pH — but if it’s an anal toy, definitely disinfect between butts. (You can use toy cleaner or boiling water).
