For those who don't know the term, a "superstimulus" is something in the modern environment that is an extreme version of something rare and desirable from the ancestral environment - something so extreme, in fact, that it is problematic.

Soda is a good example of a food-based superstimulus. In the ancestral environment, high calorie foods such as fruit were small, and somewhat rare (especially during winter), and therefore desirable - so our bodies evolved to want sweet, juicy things, and to consume as much of them as we could when they were available. The modern concoction of carbonated water, high-fructose corn syrup, and caffeine so overwhelms that desire that we are turning into a species of obese blobs, because we simply never had to evolve behaviors or sensations that would allow us to say "that's enough, I'm going to decide to stop eating this now".

There are two specific superstimulii that are relevant, I believe, for TRP.

Most modern advertising, and most modern pornography, are designed to produce a sexual superstimulus in men. The sheer amount of selection, make-up, photoshop retouching, etc. are designed to produce an utterly unattainable ideal of feminine sexuality. (The feminist community complains about this at length, talking about the damage it does to women - don't assume that this means the underlying fact is false or non-damaging; wisdom is more than merely reversed stupidity).

Part of the result of this superstimulus is a reduced libido, and a reduced attraction to actually healthy, attractive women. Does this mean you shouldn't watch porn, or appreciate a well-crafted, impossible image of female beauty? I would say no - no more than alcohol poisoning means you shouldn't avoid a finely aged whiskey. But it does mean you should watch your consumption, and make sure that you are choosing when to consume, and paying close attention to any potential long-term effects of that consumption.

In almost exactly the same way, most romantic comedies are designed to produce an emotional superstimulus for women. The plotlines, characters, background music, and so on are designed to produce an utterly unattainable ideal of 'romantic' feelings. I haven't noticed any real commentary about this from the feminist community, but that's to be expected - one usually doesn't complain when one's base instincts are being super-stimulated. Nevertheless, the results are nearly identical - a reduced ability to engage with 'normal', healthy relationships, because they do not live up to the idealized goal caused by the superstimulus.
