I have been in a warm and loving relationship for years now and the closeness and passion keeps growing with every orgasm we have. We have sex, to "completion" at least 2-3 times a week and just keep getting happier and happier.
Will it last "forever"?
I don't know and I don't care.
The bottom line is that nothing and nobody can take away the time we have had together. If it is our destiny to be together for the rest of our lives, then so be it. If not, that's OK too. This notion that "lifelong relationship equals good, anything else equals bad" is absolutely wrong on so many levels I can't even begin to list.
One would think Marnia would be one of the happiest, most fulfilled, warm and loving people on this planet. The truth is that she browbeats those around her into going along with what she says and viciously attacks everyone who disagrees with her. In fact, she behaves a lot like a lot of angry young men are behaving in the Middle East these days... men who are driven mad because their natural urges are constrained by religion and who blow themselves and fly into buildings in the slim hope of getting laid in the afterlife. Come on, you don't really think that they would be so eager to immolate themselves without the promise of 72 ethereal virgins, do you? Never mind that trying to go on a normal date in this lifetime would suffice to get them tortured and murdered.
Marnia has all the hallmarks of someone who has been in one too many abusive relationships and who has resorted to extreme measures under the guise of spirituality and healing but that is really all about control (in the power sense, not the healthy restraint sense). The title alone "Cupid's Poisoned Arrow" should be a dead giveaway. Peace Between the Sheets? Sure, provided the bed is being shared by UN peacekeepers!
The science in these books is questionable at best. Of course, they do contain enough valid research to have a good degree of "truthiness" to them but that's where their claim to veracity falters.
The problem with today's conservative/puritan societies is their (mostly religious) attempts to control billions of people by leveraging the strongest drive we have, that of reproduction. Thanks to countless priests (who are some of the biggest perverts around) of all religions, what is natural and good has become something to be feared and controlled. No wonder modern people are such masses of conflicted views and so so prone to so-called "super stimuli". Meantime, of course, violence is perfectly acceptable. For example, I know of few people with the fortitude to actually stand up to the author of these books.
The idea that humanity has lost its natural means of close companionship (paraphrasing a quote from one of the excerpts on this site) is laughable on its face. Human lifespans lasted no more than 20-30 years until very recently in our evolution... just enough time to have a kid or two and rear it to sexual maturity. Also, very close looks at our closest evolutionary cousins reveals little in the way of close companionship. To single people out as being somehow magically different is ridiculous since we share 98% of our genes with both chimps and bonobos. Bonobos, by the way, have sex almost constantly. Gay, lesbian, straight, they are lean mean shtupping machines. Result? Bonobo societies have very little violence. Do they have orgasms? Oh, yes, the more the merrier! Chimps have fairly little sex... and a lot more violence. Human societies exhibit a direct correlation between sex and violence as well. The most sexually open societies have the least violence and vice-versa.
The idea of trying to short-circuit human evolution and evolved instincts by not having orgasms is an artificial attempt to impose artificial morality (monogamy equals good, serial monogamy or even polyamory is bad) on instincts that have served us well for millions of years. It is puritanism driven by fear and deep-seated conservatism (which plenty of research indicates stems from fear and low self-esteem) wrapped in the guise of spirituality.
Can one be addicted to sex? Yes. Can sex cause problems? Yes. So can automobiles. You don't see anyone suggesting sitting behind the wheel of a parked car and making engine noises as a viable alternative for actual driving, do you?
Marnia's motives are less than pure. Her science is extremely biased and questionable at best. And both she and her husband are in dire need of some good orgasms, followed by the realization that the sun is still shining, the birds are still singing, etc. etc.
Sex is natural and healthy.
Orgasms are natural and healthy. I know. I had a strong one yesterday with the woman I've been madly in love with for years and with whom I have enjoyed hundreds of orgasms.
I am a grad student in evolutionary psychology and my other half has degrees in organic chemistry and neuroscience and is a psychiatrist.
Please, don't base your ideas on sexual health solely on these books.
