My civvie game and field 8 yrs ago was very different than what's discussed here
Hands down, if I had the time and was unconstrained, I'd stick to civvies or semi pros and avoid the pros almost completely.
I'm racially handicapped, but somewhat able to compensate through $, but am very understated / discreet.
I care little about physical appearance beyond slim / petite, but have very strong unsavoury / unspeakable desires and naturally lean towards women who can accommodate.
In my experience, taking a 22-23 yo 7-11 worker (not the most attractive in her surroundings) - on a first date that costs 3/4-1 month of her income covering dinner, shopping and rooftop bar has been the best strategy for my needs. Never had anything refused after that date, and often they continued to spend nights for 1-2 weeks after, expecting nothing in return.
I've found, the girls who are not the most attractive are starved for attention, and never been spoiled, so kind of get overwhelmed after such a date. They are genuinely grateful and show their happiness uninhibited which makes me even happier. All these civvies have rimmed me without the slightest hint from me, and always let me have their backdoor.
The civvies in jobs remotely similar to mine are too full of themselves and see themselves as a prize. It didn't take more than 4-5 such dates, 1-2 of which ended in the lousiest sex of my life to get me to swear off these women completely.
I don't frequent malls so never tried that cohort, but I imagine they are somewhere between the 7-11 girls and the snooty big company office girls.
The thing is though, IMO:
1. Civvies need familiarity over a couple of weeks at least till they will agree to a date.
2. You need to ask in the right situation ensuring she has no chance of losing face, and has privacy.
3. It is effort in the sense that you'll need to keep the pretence of a date going, but it is low effort if you do a mind blowing date.
