I have been having success with the Aneros devices almost from the beginning. Even so, each time seems to get better.
I recently had to hold off using the tool because of a lack of time and privacy.
I returned to using them this past weekend and the orgasms were phenomenal and lasted for hours.. So much so that my arms, legs, thighs, elbows, knees and ankles are sore. The only explanation I can figure is all the extended orgasms caused such tension in my muscles that I strained them.
I feel as though I worked out at the gym for hours.
