In a new study published in Scientific Reports, investigators from Brigham and Women's Hospital, Massachusetts Institute of Technology and The Charles Stark Draper Laboratory report that an ingestible electronic capsule, complete with a capsule-sized antenna capable of receiving a radio signal wirelessly, can safely power a device in the gastrointestinal tract in preclinical models. The new work makes wireless medical electronics for treating the gastrointestinal tract one step closer to reality.
[...] This work describes the first example of remote, wireless transfer of power to a system in the stomach in a large preclinical animal model -- a critical step toward bringing these devices into the clinic," said co-corresponding author Carlo "Gio" Traverso, MD, PhD, a gastroenterologist and biomedical engineer at BWH.
Other medical devices -- such as cochlear implants or neural probes - use a well-established technique known as near-field coupling to deliver power wirelessly. But ingestible devices must be small enough to be swallowed and, moreover, lie a significant distance from the surface of the body, making this technique unattainable for most gastrointestinal electronics. A new technique known as mid-field coupling provides an alternative way to deliver power to deeply implanted devices. Mid-field coupling operates at higher frequencies to deliver power two to three times more efficiently.

I am unfamiliar with my little pony and was under the impression the rainbow effect already came out of the "south" end. Although maybe that was skittles and unicorns. Well, whatever.
Another peculiar idea, project a little hologram "wrong hole aim a little higher" for those needing glasses or poor vision or its dark. Or if you use the wrong hole anyway it gives a little electric shock to remind you. Although some may enjoy that, both the hole and/or the electric shock. I know a RF burn would be painful, a guy is probably a decent quarterwave antenna around UHF 500 MHz public service band depending on local dielectric constant, electrolyte substances, and insulation level.
I did think up an interesting idea combining accelerometer features and a social media phone app so the phone could auto-tweet a numerical result of just how much you rocked her world, using the accelerometer to measure pounding accelerations and also muscle spasms. I suppose for extra financial revenue the guy could pay to have the app fake the results. You can imagine on a dudes Tindr (grindr?) profile some application integration "Assuming a spherical cow of a woman, XYZ achieved peak acceleration rates of 0.27G and 37 seconds of muscle spasms after 487 seconds of activity of which magnetometer data indicates she was in 27% cowgirl and 52% doggie positions" I could see that having quite an impact on tindr (grindr) swipe results depending on what she likes the most. I suppose to instrument the female (catcher?) performance there's mL swallowed/injected as per camera analysis. I think the MBAs could turn even sex into something as boring as financials spreadsheet. Or maybe this as an internet of things could make financial sheets as exciting as ....
