What kind of douche should I get for my bf? I'm a bit too big for him so my dick goes in him pretty deep.

His last boyfriend wasn't as big so he didn't need to douche, but I'm long enough that I reach pretty deep inside of him, deep enough to hit paydirt. I want to buy him a cheap and cheerful douche but I don't know what kind to get. I have one myself that is all bulbs and tubes, but I want something a little smaller that doesn't have rubber tubes everywhere.
