To quote Ars Technica, where I got this link:
What happens when sex obsessed engineers are presented with the complexity of the female orgasm? They invent the Orgasmatron! The small device, about the size of a walkman, attaches to a woman’s ankles and reportedly takes her to the very edge of orgasm through electrical current which proponents claim stimulates nerve centers attached to the pelvis.
I won’t touch this one — I’d probably say something sexist that will caused me to get smacked. But men, the last thing your significant others need is something else they can use to replace you in the sack. If you see these on sale, destroy them.
Man, before you know it, women will just bring stripping men with them wherever they go, sticking them in their pockets. Oh wait…they can already do that.
