I think that what makes your views so very interesting is that you bring a very deep understanding of modern evolutionary biology into your depiction of the effects of ejaculation on sexual feelings. It is quite true that one undergoes a PROFOUND change in perception after orgasm and I am certain this has evolved in order to motivate the male to seek out additional female sex partners, because this was always in their genetic interests. I'm not too sure of the effects on woman, however, because they could rarely increase their reproductive success by having multiple mates in the environment of human evolution.
Nonetheless, I can say that nothing can compare with prolonged lovemaking without ejaculation; the feelings that can swell up are beyond the ability to describe in words. For the first time, you know how it really feels to 'be in love', if I can call it that; you start saying silly, romantic things to your partner that you may regret later but you don't care because you simply feel SO GOOD! And because you don't want those exquisite feelings to end on a depressing note, you find it easy to avoid the final orgasmic climax, which always seems to put me in the dumps after any bout of lovemaking, long or short. I've come to see that when it comes to eroticism, women are FAR more evolved than men, who are essentially at the horseshoe crab level of erotic development; we have to LEARN to be sensual and erotic and it does take some time to do this.
If there's a potential drawback to these practices, it's that you seem to become much more interested in women and tend to think about sensual and erotic things more often when you adhere to these techniques consistently (but at a far more refined and romantic level). Or at least I do! It might have something to do with the male brain. Still, the pleasure you get from making love this way is orders of magnitude greater than what you experience from simply 'having sex' in the the boring old style. I hope your work leads others to this wonderful experience. Feel free to use anything I write.
