I owned a Sybian for two years and had 20-25 Providers try it out. I'll say there were 3 categories from my experiences. The Providers either:
1. We're scared shitless and did not want to try it at all.
2. Tried it and thought it was "OK, no big deal".
3. Hopped on and absolutely LOVED it, came like a freight train and they wanted me to leave it with them, lol. (I did for a couple of them).
Over half the girls were in the #3 category.
This is not a toy. You have to take it slow, warm up so to speak. The best results for the ladies are when they are alone with it. 40-50 orgasms in an hour can be achieved with experience, the right attachment, vibration, speed and rotation.
Only one place to buy them, unless you offer Lola a hell of a deal, lol:
