For me usually only the fleshlight and sometimes with a cock ring or similar.
But the OH. She is happy with two or more. Her fave is butt plug in and riding a suction dildo… love to watch that.
I will often use two or more toys on myself at once. I enjoy filling all my holes with different dildos, plugs and vibratos. I also like to use nipple suckers as well as make sure a have something pressed against my clit as much as possible.
My Oh likes to be filled. Butt plug, wand on her clit, I kneel next to her where I am able to use a dildo in her V, while she sucks my cock. She literally shakes and has orgasm after orgasm.
