I just search for reviews in my area based on ratings and age and I read a handful of reviews so I can get a feel for what to expect. Pretty simple really. Race doesn't really matter. Race doesn't really matter, although I have never seen an AA woman but that's just because I'm generally not sexually attracted to them compared to whites and latinas.

if I did, I don't think I'd enjoy my time.

and those who take advantage of and manipulate unsuspecting young girls. It's easier to see well reviewed providers that are competent and on their own.

I can recall the great thrill of being with an AA provider, and also gals of other ethnicities.

Now, that does not seem as important as it once was.

I find myself drawn to the kinky from time to time, but mostly to those who are particularly caring and somewhat cerebral.

can't remember where.  I look everywhere, and tell the newbies to do same.  However, once I find someone I think I might like to see, then the research begins.  Look for reviews, check phone, pics, etc.  I have only been with one lady of color thus far.  Had a good time with her, but for the most part, I'm not really attracted to them.

Whether they are bi or not, I don't really care.  I will say this, for a double I'd prefer the girls be bi and enjoy each other, with of course, their major focus being on me.  But for a single girl session, it doesn't matter.

Due to my living situation, I do only incall, and do prefer that anyway.  I like for her to feel comfortable in her environment.  If it's her static incall or her hotel room, I think she will enjoy our time if she is in control of the location.

Being newly divorced, I'm looking for providers who offer something I never had time to experience in the few years I dated others before hooking up with my  ex for decades. For example, I've never experienced a woman of another ethnicity. Never experienced DD or E boobs. Never experienced deep throat.  

Like other posters, I do a lot of research. I'm not as well-heeled as most here, so I'm picky about how I spend the money. I'm doing 2-3 hours plus $200 to $300 travel, so that's not pocket change for me.

I won't TOFTT. Flat out to much LE activity. Well reviewed and verified is the only way I hobby.

How do I decide who I see.

TER boards are helpful. Ad boards are good but I also like to see what a lady is posting.  I need someone who is a bit witty and has a sting to her. She can have a body that makes my cock jump but if she doesn't engage my brain in some way I might as well pound my cock into a tree.

Date-Check and P411 are nice to get an idea of who is planning visits to my area in the near future.

PM with trusted hobbiest about who they've seen or who they would recommend is a major plus.

If traveling I will PM and talk with a lady or two that I plan to see while traveling. This gives me a better feel. I've heard some ladies think this is a waste of time. I've never had a problem unless my trip has been cancelled and was always able to provide the lady at least 7 days notice.

TER is my number 1. Regional board and watching ladies comments will draw enough attention to have me look at their private websites. I like a little attitude. I like it when things are getting stirred up.

from the pace of your reviews it looks like you never pass one up. 66 so far this year works out to 2 per week.
I don't think many of us have your stamina, let alone your funding.
