Developing an emotional connection is not wise, but at the same time having a sexual encounter without some sort of connection is a pretty empty experience.
I would think that having a "sexual encounter without some sort of a connection" would be an impossible experience, or an oxymoron like dry rain. Although i would distinguish between making a connection with an SP via a barrier and direct contact with her flesh. If you are shaking a woman's hand with a snow glove on, are you even connecting with her at all?
If you are referring to an emotional connection, i'd say that i don't need that at all from an SP. All that i require from her re her emotions is, minimally, a professionally decent and civil attitude so as not to turn me off so much that i cannot attain an erection and enjoy physical pleasure while with her.
That physical pleasure that i enjoy may or may not make me feel happy emotionally. If she also enjoys the same, we can enjoy it together, but this is not required.
The pleasure i enjoy, sometimes for hours at a time, is not what i would call an "empty experience". It is what it is, and if it is an empty experience as regards an emotional connection, so be it. I can live with that, since that is not what i'm seeing an SP for, although it's nice when we can share a fun time together in addition to the moanings, near orgasms, intense physical feelings, cumming and esctasies.
In separating from an SP after a positive session, i do not feel empty, but rather look back upon it as a worthwhile experience. One that when later while masturbating alone to online porn i may recall and relive in fantasy. That is an example illustrating how experiences with an SP enhance my life when not even with her.
You might as well go and masturbate if that is all you want, a lot safer and cheaper.
There's no physical contact with another human being in that.
It has been suggested people need that for their psychological well being.
While masturbating alone you can't experience a woman's touch, her kisses, her tongue connecting with yours, or with other parts of your body, etc.
You can't feel her hair & head pressed against yours, her breasts massaging on you.
These are exciting things that erect you & turn you on. They are memories that are forever.
Moreover one can enjoy this in much variety because every SP is unique in her style, skills and looks.
While masturbating you might try to DFK your own mouth, finger your balls prostrate & butt, stick a carrot up your poop hole, cuddle with a pillow, barbie doll or teddy bear, but these aren't the same as being with a warm, moving, breathing & sexy female body that services you.
As it is written in the Scriptures, G_d said "it is not good for the man to be alone".
What you are paying for is to have that human connection, but without emotional investment. A client is happy and comfortable in what he is doing will strike that balance evenly. A successful escort will do the same same thing. She wont get emotionally involved with her clients, but on the other hand she will make a real connection with the client.
I think that is what it is really all about, when that balance is found then you have the makings of a healthy interaction on both sides.
I'm probably more satisfied with a mechanical performance than most guys would be.
Though i'm not sure the "basic pleasure model" replicant in Blade Runner would do me fine.
