I think, personally, you were a fool to even bring your wife into the discourse as an example of 'promiscuity turned loyal'. I think it's foolish to cite her past as an example of promiscuity. I think it's foolish to think it's a 'fact' that she's loyal - it's not a fact, it's a self-serving supposition.
Further, even if your wife qualified as a sex trade worker, at no time did I say that 'all' people who screw, say, 300 people are hardened, as your faux refutation implies. I think my language and level of specificity was perfectly appropriate for a discussion. All talk in the social sciences allows for distributions of behavior that have variations 'built in'. So when people say "Smart kids get good grades" we allow for the possibility of 'some' smart kids getting poor grades. But this in no way negates the value of our claim that 'Smart kids get good grades" because, well, most of the time they do!
You say:
And yes you claim that people who have lots of sex can get hardened.
Nope. What you have said above is called The Straw Man Argument and it's a form of crooked thinking, or deceptive argument. Here, you create an 'easy to refute' claim I never made, and then you proceed to knock it down. I did not claim that having sex many times with one partner hardens you. I consistently referred to 'number of partners' and I consistently cited number of partner figures that you fully know are no where near the figures for your wife. However, I don't know her. Maybe she had sex with hundreds of men, and if so, I'd say she's 'harder' or, perhaps if you don't like that term, more 'callous' to the feelings of people than she seems. Perhaps having sex with hundreds of people isn't a 'callous' or 'hardened' approach to intimacy in your own mind, but I think the 'hardened' adjective fits. It even fits with 'casual' sex, which carries the connotation of high 'emotional distance'.
I don't need to prove my intuition. What I needed to do was to give 'reasons for believing' that my intuition has merit. And I believe I've done so.
The rest of what you're saying is just hand waving and bravado.
