I love vibrators, especially high quality ones with customizable settings. I prefer soft silicone because it is silky to the touch and fully sanitizable. My favorite brand of vibrator is definitely Lelo, which many of my provider friends would agree with. I have a few of their vibrators and love all of them.
There are all these great high(er) tech vibrators just starting to enter the market these days. I just got a remote control vibrator where the remote control has motion sensor technology and uses your movements to control the intensity of the vibrator. In one mode, the more you tilt the remote the harder it vibrates, from 10% intensity to 100% intensity. Great for masturbation, and also great in Toys for Boys! Having a remote that uses such an intuitive motion to control intensity instead of having to press buttons on the remote makes it was smoother to use while one is distracted.
It is also fully waterproof which makes it easy to clean and sanitize.
I haven't gotten to use the remote control vibrator in public yet, but I am hoping to get to... Someone better take me for a naughty dinner date sometime soon.
I masturbate with my new vibrator all the time but I've only gotten to use it with one client so far (mentioned in my most recent review) and he loved it!! I enjoyed the precision of control that I had over the intensity/pattern of vibration. Seemed like something one could get really skilled at with practice... and I definitely want more practice!
Great topic!
