Johnny to me sex is only one aspect of why I've gone to AMPs for several years. If that was the case I would opt for the 30 min. session every time. I enjoy the companionship emotionally at times as much as I do physically. In fact, just last week I went to see my ATF for an hour and we just laid down and talked at my request.
In terms of personality, my favorite providers are the ones that have shown some level of ability to have a conversation, sense of humor, or something that sets them apart from "just looks."
I don't lie to myself. No need to. Like my signature implies, I know who I am faults and all. It's everyone else that has trouble accepting that, not me.
But under your definition, objectification would apply to every relationship between a man and a woman. Men need sex and companionship while women need companionship and security. Both are using each other as a means to and end. Thus, every marriage would be an objectification of the other just as much as me going and visiting an AMP. The commodities just tend to be more basic.....and in some cases, not.
