Based on the unusual shape it isn't immediately obvious what the best way(s) to use this interesting toy are. I say best - because there is clearly no 'proper' technique.
Although when we first bought the PureWand my wife taught herself how to orgasm - even squirt with it - then gave me some tips. But now she says that my technique is better than anything she can achieve. It's all about angles really - from my vantage point I have more freedom of motion and better angles.
The intensity of her experience with this toy limits it's use to about 2x per month - but when she hands it to me, I know we're in for a very wet and orgasmic session!
So what tips and techniques work for you and your lover?
