Gags are wonderful, just start slow, make sure you can breathe OK as Barton says. If you have troubles breathing through your nose it can limit things somewhat.

Just don't expectto wear one too long the first time & never never be left alone.

Depends on the gag too- some are very uncomfortable, one of my girls has one she can only wear for 10 minutes tops.

Be prepared for a most pleasant experience!
