I generally won't see ladies who are more than 2-3 inches taller than me for the reasons set forth above.

I am 6'5", so I taller than most providers that I have met.  sometimes can be a problem with the short, petite ladies.  if height difference is too much, can't do missionary so left with doggie or cowgirl

don't have too much problem with mish with most any size girl. In fact my GF is 4'10" and mish is one of our favorite positions. Now where I do have problems sometime with shorter girls is doggie. If the bed is high enough and I squat just a little we can make standing doggie work. Traditional  doggie can be a problem sometimes with shorter girls.They have to keep legs closed with mine on the outside to even get close to making it work.But that position can make some girls so tight it can cause other problems. Legs open doggie gives the best visual and makes it easier to get in but the girl must be tall enough. Now standing doggie where we both stand is out of the question unless she is over 5'3" and I squat a little. I love that position but it's so exciting to me I can't stay in it long but I love practicing my stamina in it every chance I get....lol.....If you have the room and the time you can get creative with most all the positions though.

I actually like being with taller providers, and I'm really quite short. I have decent game though, so I find I can pull women within a certain size of me -- but really have problems with the Amazons.

If I'm paying for it, I figure, why not get something I can't get in real life? It can be awkward, but I'm paying, and my enthusiasm usually makes up for it.

A man being taller.....

is usually always the case with me as I am only 5'3" barefoot lol Now when I put my heels on ofcaorse I look much taller (they make great handles in certain positions)  
Ya know I never thought of that being an issue for you guys but I can see your point. Me being short though I do have to pull out my liberator ramp often lol  
Hugs and kisses
