Really?
I started reading your reviews and just got annoyed. Your mediocre and bad experiences are all BackPage providers with bad, mediocre, or NO reviews.
Your good experiences are with women who do NOT advertise predominately (or at all) on BP - they are with EROS, P411, Date-Check, or they advertise HERE and have professional websites. They charge 300 or more for an hour of their time, have multiple pages of good reviews, and judging from your scores, gave you everything that you wanted.
Even IN your bad reviews, you keep saying "you get what you pay for" and "I should have known better".
Yeah, you should have.
I just did a couple of searches for the Chicago area - since you didn't give ANY info about the physical type of woman you like, I left that blank and just searched for "women with min. 3 reviews, MIN looks score 8, MIN performance score 9, and price up to 500/hour" and got THIRTY hits THIS YEAR, didn't even count back to Dec 2013. Then I upped the ante, "women with AVERAGE 9/9 and max price 400/hr" and got EIGHT hits this year.
The women are out there. Search undr strict parameters and read the reviews. Narrow it down to a few choices and then ask guys in the Chicago area for advice.
