Sex is about being aroused by someone else and being happy in your own body. If neither applies to you, it's time for a change. All the gadgetry in the world won't make you pleased with yourself or attracted to another person. Electronic sex is another way of faking it. So much for the moral high ground.
Electrical pulses are sensitive to their environment.
I don't want to be routinely doing the beep in Waitrose carpark, only to find myself writhing over the windscreen like a photoshoot for Nude Reader's Wives. I guess a hearing aid is safe enough. I have not read whether the device comes with a timer. That would at least leave the element of surprise that comes with real sex. It might be a turn-on, wondering where you'll be, and with whom, when the first tingle starts.
