I have taken MORE than a few of the big dicked trannyescorts BALLS DEEP but sometimes a well but not overly hung shemale like Cindy of Sandiego (8" pretty fat) I cant. I douche the same way and have the same desire but cant take it all or I do and It REALLY is painfull without all the pleasure. Im not sure if it has to do with the paticular tranny or the cycle of the moon but how could I take EVERY INCH of Vanilla, Ednita, Karen Cummings, lola Malone ect and have such extascy and then have a 6" cut little tranny from the suburbs off backpage make me a squeeling little bitch until they cum? Body positions dont seem to matter though cowboy seems to hurt the most....Maybe the big cocks slide past the prostate and the smaller ones pound into it? Missionary is my fave....Your thoughts?

For my subs I generally  have  them  on their  backs  with  their  legs  in the  air, HOWEVER… I do have a few pillows under their hips which seems to lift their pelvis
Which seems to relax them so I can go in as deep as I like……..just FYI

yup you just answered your own question. Small cocks pound directly into the prostrate while big ones slide past it instead that is why you can't handle 6 inch but you can take 9 inch.

Yea that was the only thing I could come up with. It was hard to figure out how Ednita/Karn Cummings  could give me such a hard balls deep pounding and after getting used to their girth it was extacy and the small cocks hurt. I wonder if some guys can take all sizes without any pain. Maybe after all the prostate pounding ive take by trannys over the years my prostate is enlarged....

For me it's position and girth.  I can take it deeper doggie than missionary.  Thick and long is easier than thin and long.
