Consumer electronics with a twist. This year’s CES had a plethora of sex toys avaible for people to examine. The artile I linked to talks about a couple of interesting vibrators, a sperm test, and a warming lube dispeser. Didn’t see anything about connected devices, but with IOT security issues abounding, I’m not sure I would recommend a wifi based device these days. Bluetooth, now there is an interesting option.
You may enjoy these though if you do want a wireless thrill. The cam girls all seem to.
