Strap-ons as sex toys

Strap Ons: A strap-on means more specifically, a strap on dildo or vibrator. Usually a dildo will be connected to a harness that is worn around the waist. It's not uncommon to see a couple lesbians in a video, and one of them wearing a strap on. The dildo would be sticking out away from one woman's groin, just like a real erect penis would be sticking out of a man. The sort of intercourse possible with a strap on is similar to male-on-something sex, so the woman wearing the strap on could be role playing as a man.
