Don't be so self conscious about your height. Short folks like us will have a much easier time hiding when the zombie apocalypse hits.  

How about 6'?

I've seen a few providers in that range and I'm about your height. All wore heels but remember that things tend to even out when you get horizontal. If you're not going out in public, there's nothing to be intimidated about and honestly, they've all been wonderful with my height-challenged problem.

FYI, there's a beautiful Polish bikini-babe girl downtown around 5'11". One of the best times I've had and I'd see her again if she ever came out of downtown.

i love it. I am 5'10 without heels, and the shortest guy I have seen actually was a dwarf...super awesome guy though and I never would've known. I played nurse for him, and it ended up being a great evening.

I wouldn't have a complex about seeing taller girls. That ca be sexy as hell IMHO. I say go for it.

first one to know when it floods! lol (I'm not tall either!)

So what does it matter, WAIT I take that back when we are horizontal you are always taller then me because the lower head is at full attention and I just do not have one of those things!

It can look a little odd when you are out if you are self cautious about it, if not it looks great.  Look at Vern Trower, he dates models who are all 5'10 plus and he is what, right around 3ft.  The thing is if you are going to go "out" with that height differential OWN IT!  Otherwise it just looks uncomfortable.

Tallest I've seen is 5'10" and I'm 5'7" so I know where you're coming from.  I prefer to see shorter women as well.  There are a few women out there who I'd like to see but they're 5'10" or taller.  It does sometimes make it awkward when you're both standing and kissing or standing doggie.  But in general, I've always preferred the petite girls so I guess it isn't out of the norm.

Jeez i'm just scraping 5'5'' without heels .......

....you'd shut me out? lol
Shortest client i've seen he was 5'3'' (I didn't even ask if he wanted me to take my heels off I just did or hell i'd have felt akward lol.  
Self-conciousness about height is why in civvie life I normally date men 5'10'' and taller.  
In the hobby i'm luckily shorter than 90% of the people I see lol if I don't wear 5 or 6 inch heels.

I'm only 5'7" and have no preference on height.

my preference is that she be my size or shorter.  Oh, and unless she 4'11"  she can leave the 6" heels at home.

In the bedroom creative minds can make any size work.

myself and I understand what you are saying especially if you are going out and she is wearing 5 inch heels. But in the bedroom it shouldn't matter much, you can get creative like use a chair to climb on for standing doggie (LOL).

It's always the short guys...

I'm somewhere between 5'4 and 5'5 and I love the tall ones, 5'9 is the tallest I've seen, but I did date a 6'1 girl in college.  
Seriously, don't worry about it-I always ask the ladies during my initial contact if they have issues with height, and its never been (n=4 provider sample).  It also helps if you're strong and flexible, as you may have a lever advantage in...  certain positions.  
My $0.02

'm 5' 11" and LOVE the short ladies. The shorter the better. 4'9" to 5'2" are my absolute favorites. while horizontal, things are a bit more in line. While vertical like standing doggy there are easy solutions. I have run into situations where even a 5 foot gal and I didn't line up right while in standing doggy due to the bed being too high. Shit, just yesterday in fact. She can spread her knees further apart and if that isn't enough to line things up just bring her to the corner of the bed. She can lay on her tummy on the bed with one knee hanging down on each side of the corner and while not actually on her knees it's nearly as good. It's missing a little if she is a gal that likes to try to push back but otherwise it seems to suffice
