Mmmm...we don't really have anything that's a team endeavor, but DH has a cock ring he sometimes throws on, and that's a nice added bonus. I also like us wing my vibe whilst getting my freak on...it's not just for solo time.
DH has one with a vibrating nub attached to it, so that his dick vibrates and the nub hits the clit when he thrusts (since you asked!). I'm pretty sure he got it OTC near the condoms, made by Trojan. Love love love. It just makes things feel more intense.
