I've rarely had a lady recommend a friend. In fact I can only think of one example in the UK. However, I love the idea. The more the merrier I say:-)
In fact tomorrow I shall be sampling just that very thing:-)
My best experiences by far have been at the now (sadly) defunct Lady Marmalade Parties in London. You haven't lived till you've buzzed from one moist, nectar filled flower to another for 4 consecutive hours:-) I once tried a follow on 4 hour session and that very nearly killed me:-)
The equipment was literally rubbed raw:-)
Ahhhhhh good times
