Well there is the first problem of the substantial $$$ the sybian costs, esp. if you want to purchase it with at least a few attachments. Kind of tough to justify spending $2,000 on a really, really cool vibrator when you've got credit cards carrying balances
Secondly, some women are multiorgasmic, they can continue to be stimulated for a long, long time, riding the peaks and valleys continuously. Some women, however, have one really enormous climax and then they simply cannot bear to be touched, any stimulation is dreadfully unpleasant and hypersensitive and makes you state, uncategorically "
Enough!" (I actually believe this is due to anatomic variations, much like some women simply cannot climax strictly through intercourse). I don't think girls who fall into category 2 will enjoy a sybian nearly as much as the girls who fall into category 1. I'm in category 2.
