First of all, you do realize this is the first and only time you yourself have posted any study? Relax. I don't know what it is about you guys on here and your inability to have a simple conversation without getting emotional and hurling insults.
And please follow your own line of logic. You are the one who brought up sexual dimorphism as it relates to differences in desire between the sexes. You cannot jump from talking about a specific topic, to then moving back into the broader topic (sexual dimorphism in general) and then pontificating about the "overall" effects of it and ignore we were talking about something quite specific. To put it plainly, you would need to post evidence to back up the specific topic of sexual dimorphism and sexual desire to prove your assertion that men desire sex more often than women on average. Your first link is moot as a general conversation about sexual dimorphism was never the topic of debate anyway. It was simply something you brought up in relation to the topic of conversation, which was sexual desire in the sexes. Your link doesn't talk about that.
My theory of it being more social than biological is as much of a theory as your assertion that women on average are not as horny as men. And despite your claims that you're not agreeing with it not being a reason for men to cheat more, etc. it is an excuse that is being used by men who do believe that and it is a claim you've made repeatedly in this thread.
Here is a link of mine, to an article about a study that was conducted and actually addresses the conversation at hand:
What Do Women Want? - Discovering What Ignites Female Desire
If women can be physically aroused by a wider range of sexual stimuli, this could actually be said to indicate a stronger sex drive in women, could it not? And when you are able to see that it is not acted on as much as men despite the physiological necessities being there, would it not lend credence to the idea that when it comes to sexually behavior it is heavily due to social influence?
We also see in this study evidence that female sexual arousal reporting, due to a literal entire lifetime of social conditioning, is often unreliable and doesn't actual match up with their physiological response of sexual desire.
Another study (of many) that would also indicate another reason to dismiss your earlier attempts to use sexual desire reporting to say men's sex drive > Women's:

When men and women thought they could get caught for lying, they reported true numbers that may not have reflected their gender stereotype about how much and how often they should having sex. When they thought they couldn't get caught in a lie, they lie their behinds off in favor of their gender stereotypes.
And here is another study that even specifies that biology can actually be influenced by social factors, something those of us in the medical field have known for years:
Nature vs. Nurture and Sex: Why the Fight?
We also know that in times of great stress, many biological changes happen in the human body to adapt. In times of great sorrow and happiness/overindulgence as well. To tie that directly, so as to not be misunderstood,
Now is this irrefutable evidence that sexual behavior is mostly social? Absolutely not. There are very few things in this area of science that can be said to be irrefutable. Every new study debunks the last. But do I feel there is far more evidence to say that sexual desire differences in the sexes leans more social than biological? Absolutely.
