Yes they do.
But only suplement in prolong the orgasm that has already hit
Haven't tried them yet, but was looking at them in the store. Maybe!
Yes it is a turn on. The feeling they create. You can some that are about an inch in diam. with steel balls inside. Inserted and left in, when you walk around, the steel balls move inside the outer plastic ball creating a vibration/moving sensation, which feels great!
Yes, I too love the ones with the steel balls inside.
I like them most of the time
