why did I wonder about this for a year - you cannot imagine the orgasm you can get with this thing on low ... and do get the attacment set - this is how you can make yourself squirt like your Dom makes you when you are bound ... it is amazing... and scary not sure if I should have told my Dom about purchasing this new toy ... Afraid to try the high switch ... giving serious consideration to buying the graduated power switch ... worth every penny - just do it
