Rather than stroking, the Octopus pulsates. The pulsations give highly pleasurable sensations, but ones that are qualitatively different than stroking sensations. The Octopus is well constructed from strong rubber/plastic that grips the penis, flaccid or erect. It might be especially good for guys who have erection problems. When attached to my flaccid penis it was surprising to watch it grow hard so fast. It comes with a remote control built into a watch, or it can be controlled by buttons on the Octopus itself. While it is possible to stroke with the Octopus, this isn't necessary. Achieving orgasm happens when the wearer adjusts the pulsation intensity gradually until the Octopus has the proper frequency to pull the orgasm out. It is a qualitatively different orgasm, a slower building, semen leaking, longer lasting and more intense orgasm than with stroking. When your partner is in charge of the pulsation, exquisite and prolonged edging is possible. Good for couple or alone play. A single charge was good for several sessions. Highly recommend this toy.
