Lesson 18: Electro-Play
Electro play is using electricity to stimulate someone sexually. In this case it is electricity to the testicles. This one is actually fairly safe. It is also expensive. There are lots of good products out there that have been tested for these kinds of activities. If you do not have heart problems or other circulatory problems it is something to look into. Never use a device that uses more than 9 volts. Never use the devices above the waist. Hands count as above the waist. As long as you follow those rules there are no time limit or power limits. It is reasonably safe.
