Well, not exactly. That is to say - never followed that technique specifically. Although, it does sound a bit like carefully rhythmic multiple orgasms which - because I am a very lucky woman - I do have quite regularly. Interesting, though. And maybe something we'll have to give a try!
Anyone else out there given this a whirl? We'd love to hear about it!
