I play with mine sometimes. I agree with all who have said it's relaxing. Sometimes, though, it just turns me on way too much and I have to stop
They are fun and I personally love the shape of mine. I do it subconciously too. I'll be reading or on the phone or soemthing and realize I've been playing with my boobies. It's nice when they get free of the bra and they're all sensitive...ok..I think I'm gonna go take the bra off now...
