honestly I'd support a program where the more you work out the lower your insurance premiums would be. Pretty hard to cheat workouts with Apple Watch when it has a heart rate sensor and all that.
It isn't a horrible idea in the abstract but it seems likely sex would trigger data similar to most workouts. Also, there are people who eat healthy but don't have time for the gym. Conversely people who go to the gym everyday but mostly to try to burn up their Big Mac combo meal. From an insurance standpoint, I think HA1C is the only measure we could like use. Things like BMI, etc. are too varied based on genetics.
You generally get what you measure, so be careful to measure what you want to get. Isn't elevated heart rate connected to better health outcomes no matter what physical activity it comes from? Why should the insurance company care if some of it is sex instead of, say, running?

Accelerometers and GPS would allow them to narrow down specific types and patterns of sex as well. Lots of sex in cheap motels == high risk. Correlating customers together..this one has HIV, and appears to be having sex with this customer == high risk. Fun.
For health (which we're talking about), life, or car insurance (since a bunch of UK insurers also have "safe driving" apps that earn you points, etc.), yeah, sure, why not?
Because obviously they can use those to profit by dropping eg people they diagnose (or just infer statistically) with serious problems before they develop, or raise their prices, etc.
This is not about some extra win-win motivation to be healthier...
It's about turning risk (which is supposed to be what insurance companies are paid for) into rent-seeking...
That reminds me, back during the Tamagotchi craze (which coincided with the Pokemon craze) there was a virtual pet Pikachu that rewarded you for walking (it was a pedometer) and the screen would show Pikachu walking while you were. It was pretty cute. Well, it wasn't long before my little brother figured out how to "cheat" He put it on the washer. (I think dryer worked as well)
What I would be afraid of, here, is that if there are signs that big data can uncover that peel out some catastrophic disease from your workout data that would mean your insurance company knows you're very ill long before you do... It would extremely tempting not to do something about that knowledge that helps the company even if it hurts a soon-to-be-dead-anyway person.
