r/ringgag

Hello friends, as the title says, I and my girlfriend are looking for a nice gag. We already have a cheap and gag. Which is useless and too small. We want to use this gag especially for increased drool.

We were thinking of buying a ring gag. But in my country we don’t have a lot of choices and all of the ring gags are solid metal without a protective layer. ( I checked everywhere)

My questions:

1-) Is metal ring gag bad for the teeth or in someway dangerous?

2-) Is normal gag ball(breathable or non-breathable) as effective as ring gags for increased drooling.

3-) How big should it be? I was thinking about 4.5 cm.

Thanks a lot!
