The response to this poll and the comments are very interesting. That most people are aiming for monogamy, even on a forum whose goal is the study of having sex with women, explains why the world that we are trying to create must remain hidden, even from those that it benefits.
Let me be blunt. Every single man in the world is living in a polyamorous relationship but only a few realise it consciously. The rest engage in subconscious behaviours that betray the fact that they know it genetically, while consciously disavowing any and all knowledge. This is called cognitive dissonance.
Here is how I know. During a one month stay in a hostel I experienced high and low energy states. When I had low energy and was incapable of picking up, guys would jealously guard their girlfriends. When I had high energy and was at my most dangerous, guys would pretty much leave their girlfriends where I could easily hit on them.
So why this counterintuitive behaviour? My best theory is that guys know (on a genetic/emotional level) that their girlfriends are going to have sex with other men. The only thing worse than that would be to then lose their girlfriends to those men. Furthermore, the amount to which I want to monopolize the women I am seeing depends on how low my energy state is. That is, when I have high energy I don't care about relationships at all, but when I have low energy I do. Therefore guys would prefer (subconsciously) that their girlfriends have sex with a happy, high energy guy than with a depressed, low energy guy.
Many of you here set jealous conditions on your relationships and do things like going through your girlfriends' phones looking for texts and stuff. This feels smothering and stifling to them. Eventually, they get sufficiently annoyed with your actions and get into a fight with you then storm off. And what do they do in those few days while you are apart? I think you know what I'm getting at here.
The third post in my "natural axis" thread has a part during one night where I had massively high energy and these guys were practically abandoning their girls on the dancefloor even as I was grinding them. It made absolutely no sense EXCEPT through the explanation I have proposed here.
But if someone has a better explanation then I want to hear it.
