Earlier quoted context omitted.
You suggestion kind of sounds like: Let's teach kids how to grow an apple tree by giving them apple juice. Consuming the benefits of having a woman sexually interested in you is a very different skill from creating that interest in the first place. So they would just pay to skip all the steps that they are bad at, thereby never learning them.
I think that may happen in some cases but they would also learn that sex is likely not what they imagined it to be. Its just something that people do together sometimes. I think there would be emotional growth after the fact.
If you're paying someone to live out those fantasies, you're probably not going to experience "normal" sexual relationships.
