A sedentary lifestyle leads to a reduction of testosterone. Simple as that.
We have a problem with our tap water whereas estrone, estradiol, estriol, and ethinylestradiol are forever chemicals that are not removed from the water. Hormone replacement therapy and contraceptives are >90% of the source of these.
If you don't filter the water you drink you are experiencing low grade intake of estrogens. This is what water filters are meant to remove and they do. Hence why we have such a huge 'water filter' industry.
It doesn't stop there and why you are partially correct. BPA: https://en.wikipedia.org/wiki/Bisphenol_A
The problem with BPA is that BPA is a xenoestrogen, exhibiting estrogen-mimicking, hormone-like properties.[6] Although the effect is very weak, the pervasiveness of BPA-containing materials raises concerns.
If you microwave plastic container holding food. You almost certainly have put a xenoestrogen into your food. Sure we have sort of banned BPA from baby bottles but we haven't done anything to the average person.
We are still going: https://en.wikipedia.org/wiki/Phytoestrogen
Soybeans, Flaxseeds, lentils, etc. All pretty high in isoflavones. Which act like estrogens. Many studies have proven that eating soy or similar foods while in menopause gives benefits in reducing problems. Because of 'conflicting studies' and therefore there's no conclusions and we just keep going forward.
When you put all of these sources of estrogen together. You are absolutely producing a hormone replacement therapy on tons of people.
when women get too much estrogens they become 'estrogen dominant' obviously. https://chapelhillgynecology.com/signs-of-estrogen-dominance...
You also get general problems of HRT symptoms in men.
I do not find this surprising. Most of my friends and I also value the other person‘s orgasm over our own, regardless of gender.
The real problem is that most people have too much ego to go read on the internet how to give good orgasms
Has this paper acknowledged same-sex relationships, at all?
(Apologies for the sex/gender conflation)
Why comment at all?
You mean that people need to be in the right mental state to really cut loose, enjoy themselves, and feel trusted around those they are the most intimate and vulnerable with?
the _hell_, you say.

"And so there’s this way in which contemporary profits are supported by free labor that women provide in the home. And this free labor actually ends up trapping women in dependent relationships, largely with men, and that means, ultimately, that women get stuck because they have all these care responsibilities for which they are not paid. They are stuck in the home, generally financially dependent on a partner or spouse, and that unfortunately leads to people being in unhealthy or abusive or unhappy relationships."
I've lived in a few different Western countries, mostly very developed, and most of what I have seen is women working and men sharing many responsibilities. So this seems to me like a terrible starting point to build that thesis upon.
Perhaps the book itself has some actual data?
