IMS basically sounds like the result of a SSM. I don't see it as a cange in chemicals, It cam be both cemar.
I post on a forum where 40-60ish guys claim they want more of something. They have a lovely W, sex happens 3X a week, they get and give OS, they have the good job, community respect, etc but are not happy. some don't want a sexual R with their W who is described as almost perfect.
it is a change in his marriage that causes it So there is no single cause for IMS and don't discount age playing a factor in something similar to andropause. Andropause isn't a pause, its a gradual decline.
Cemar change your thinking. Lack-O-nookie is a problem just as a lack of desire is a problem, just as a lack of appreciation is a problem.
i don't get head. If I did, I don't expect BB to swollow. Even what we have or don't have in our M, I work with what I have. Am I thrilled about what we have, No. Am I looking for the magic bullet, No. Am I looking for ways to improve what we have,yes.
Something interesting I have found out about testosterone, the one sure way to reduce testosterone in men is to have them marry. Maybe because they get it milked out of them more often or maybe marrien men don't produce as many killer sperm (sperm that attack other male's sperm) as single guys.
http://members.shaw.ca/tfrisen/chances_of_you_existing.htm Kind of sperm: An average man produces 3 kind of sperm: (1) Killer Sperm constitute about 83% of all the sperm -- these are sperm that attack any sperm from another man that may be in the woman. These sperm carry a lethal dose of poison in their head, seek out foreign sperm and inject it with this poison, killing it. Apparently after a few injections the Killer Sperm has spent all it's energy and also dies.
(2) Blocker Sperm constitute about 16% of all the sperm -- these try to block entrances and storage places so that any sperm from another man cannot reach the woman's egg.
(3) Egg Getter Sperm constitute about1% of all the sperm -- these are the sperm that can possibly fertilize the woman's egg if they ever get there.
So 99% of sperm make war on other men's sperm to annihilate them so that they won't fertilize the woman's egg, and 1% have the potential to fertilize the woman's egg.
There are killer sperm, there are blocker sperm, and there are egg-getter sperm. Number four is family-planning sperm.
Killer sperm kill any sperm from other males found inside the female. Blocker sperm join flagellas (the tails they use to swim) and block any approaching sperm from other men. Egg-getters go for the gold in that great race we call sex. And family-planning sperm (cute name) kill any and all sperm it can find.
Helen Fisher and her research asociates say on: http://www.dhushara.com/paradoxhtm/homo.htm Human males have medium sized testicles and killer sperm consistent with moderate sperm competition, but less than those of the larger ejaculates of promiscuous chimps. As a proportion of body size human testicles are five times the size of gorillas and one third the size of chimpanzees (Ridley R559 21). In the Cosmopolitan survey of 1980 half of married women under 35 had been unfaithful and 70% of those over. Likewise for men sewing wild oats is accepted as natural. Human males are about 10% larger than females consistent with moderate polygynous competition, but not the large harems of gorillas. Men are more aroused by images of males competing for a female than readily available females and produce better sperm after watching such images (.Biology Letters doi:10.1098/rsbl.2005.0324).
That is what some people say but if you believe marriage lowers T, so be it.
