To practically every woman out there, you are a dick with a salary attached. Which is bigger? Are they both 'cute'? You do realize some women want 'cute' over 'holy fuck that's hot'.
Now: you have every right to be that! Go on bragging about it, and being a fixture on that dick carousel. Just remember to get off before you get replaced. You seem to think that you can stay on that thing into your 40's and well,
EL OH freaking EL.
At 40 you have to have a fucking wonderful personality for a partner to look past how much your making, especially a 20 year old. I'm not posting this because you've offended me, or because I care. Consider it a professional slut who's had his
own very rude wake up call recently giving you a heads up as to what happens when the physical attraction melts away. That isn't to say there are not hot 40 year old's, but they're off the carousel already. It's too risky. They've built their own, and the people who make it up know what they are. But those people will fade away with time. Sometimes much faster than you think will happen.
I've spent enough nights with lonely 40 year old's who are making silly amounts of money who are very, VERY hot to know that if you are fundamentally so damaged that you can't allow someone to get close to you it doesn't matter how good of a catch you are. Eventually, people will stop trying. And if you enjoy being chased after over doing the chasing, which it sounds like you do, then you're going to be put in a very awkward spot when you reach an age where the only women left are the best ones at running away.
So go on being your bad ass self, and I hope you find someone you can settle for and get off the carousel. But don't state matter-of-factually that all women are the same creature. To answer your question:
Why making a decision based on cost/benefit is objectifying women?
Because that is exactly what you are doing. You are comparing women in a way that is:
"What is better, and what do I want?" not "Who is better, and why do I want them?" and you are so god damn self important you can't see the difference. As I said before I typed all that, women see this and
instantly decide how far they'll take it but only up to sleeping with you. And then they'll run for you to chase, or chase after you. It all depends on how you lead. You have established yourself as the leader, and better not years down the road decide you don't want to anymore or you'll have yourself a very might train wreck when she tries to take control.
