My Chinese uncle has a pair of these (albeit larger and more... ornamental?) to roll around your palm during meditation. - Uhm... disturbing.

If you're lily is dry, I'd suggest lubing these little guys up to make for a smoother entrance. Once they're in, I've found it fun to roll them up and down with kegel contractions but after a while it gets tiresome and boring. I think the point of these are to just keep them in there for as long as you can without letting them slip out. I'd suggest you try this only at home until you're comfortable holding up the weight of these little things. It would be a nightmare to have them in while you're taking your daughter to ballet (or something) and CLINK - one falls on the floor. (Can you tell it's a fear of mine?) So I'd encourage you to do some "endurance" training at home (preferably not on hardwood) before you bust these out in public.

I've always hoped to feel the clanking against one another (I've heard that the vibrations are pleasurable?) but I've never had success. Short of jumping on a trampoline or bouncing up and down my house (both would be weird) I don't know how else I could get them to move around inside me without kegel manipulation. Next time I ride my bike down a cobblestone road, I'll be sure to let you know how it feels.

These tiny gold-colored metal balls have a diameter of 1.5 centimeters and are useful for temperature play, as they will retain a low temperature for a while. Not sure why anyone would want to warm these up before putting them in, except to reduce the shock and subsequent lily clam-clamp. A cold metal thing trying to enter my crotch has never been the epitome of sex for me... It makes me want to put on all my clothes and jump in a hot bath. Yes, with my clothes still on.

The balls come in a plastic container that looks tacky and breaks easily, so after making my purchase, I transferred it to a small cloth bag that used to hold earrings.

Smooth, hard, and slippery, I'm petrified to take a pee while these are in. I hear about people wearing them all day, so I assume that people don't take them out when they go to the washroom - I'm just... so... scared. Scared to lose them down the toilet, but mostly scared that a co-worker will hear a "CLINK" when I sit down, or WORSE... it rolls under the stall door and my boss thinks I've just laid a little golden shit.

As a plus, now when someone suggests you're a wimp, you can tell them that you have balls of steel.
