I have used the Aneros a few times and it is awsome...I love it. I have never had such powerful orgasms. My one complaint is that when I really get going, the tab starts to become painful on my perenium. it moves around and hurts quite a bit...and distracted me enough to postpone orgasm a couple of times. I tried putting a washcloth between my skin and the tab...and that helped a bit, but am I doing something wrong? Any suggestions?
