What's the best ball gag?

 Me and my boyfriend have been taking about getting some odd bits and pieces and one of them is a ball gag. The only thing is there is so many I don't know what's the best. My boyfriend has a fairly large mouth, but mine's rather small about 4.5 x 3 cm, while my boyfriend's mouth is like two, three times bigger than mine. I've read a few reviews and people mention about the balls smelling or tasting funny or the facial straps being really uncomfortable. 

So I was wondering if anyone has any ideas which are the best and maybe have interchangable ball sizes (that also don't taste funny) so it can fit both me and my boyfriend. And comfortable straps that hold it firmly in place so neither of us can spit the ball out or make much noise. 

Looking forward to the replies.

Silicone ball gags should be flavour free after a good wash, so they're always a good bet. Generally you'll get some taste from most other gags, but giving them a good wash before use will help and you can apply flavoured lube. I personally like the taste of rubber gags and the dry texture stops people dribbling so much.

To measure for a ball gag, ask your partner to open their mouth wide and measure the space between the two sets of teeth. You want a ball gag with a diameter bigger than this measurement to effectively gag him.

1.75 - 2-inch diameter balls do it for most folks and I certainly find them a stretch with 2 inches between my teeth when my mouth is open at its widest.

The balls don't always have to be large, a tight fit will prevent the ball from being pushed out of the mouth. Straps often need extra holes adding for a perfect fit (much like belts and shoes!), so if it's a little loose or tight, then an extra hole should stop things chaffing or sagging.

Sorry, I can't think of any jokes about testicles!
