Humble D and Little Lenny:
You guys are brave to post your feelings here.
No doubt you are young single guys who are still looking for a seductress/girlfriend/lover all in one. Take it from an oldtimer, it is possible, but the same rules apply to a relationship with an MPA or dancer or SP as they do anywhere else. Do not confuse business with romance. When you pay for service, that is a business transaction. Do not confuse it with romance.
It is possible to have a girlfriend relationship with an MPA, dancer or SP. But to judge whether it is real, judge it based only on what happens outside of the business place.
If you see her frequently and go out with her. She has you back at her place often or you have her at yours. You have wonderful sex outside of the business place (without paying) and she pursues you as vigorously as you pursue her. That is the real thing.
Also remember, in general, (remember, generalizations are limited) ladies who work in the sex trade, are more screwed-up in their relationships than ladies outside the sex trade. So even if you have a relationship with such a lady, it will likely be short and stormy.
Just my advice, do with it what you please.
Cheers
