Hi OP and others - I can give you some thoughts on a variety of different ways to approach WS in general and GS specifically but won't waste anyone's time unless there is interest.  As always this would simply be my opinion based upon a ummm thirsty quest for knowledge in all things sexual and I do enjoy sharing and receiving thoughts from like-mined folk.  On another note isn't it nice to find a thread with good content, polite contributors and respectful acknowledgements - kudos to all above I've really enjoyed reading through this, cheerio, Vin
