I´m a vers bottom with a height of 175-178cm and, as one might expect, when looking for a top - I typically go for someone my height or taller. It comes with the expectation of wanting to be "dominated" although for a hotter guy (height is not the exclusive factor to "top energy"), I may go as low as 170cm - but I find that 167cm is already too short for me, for a top.
I´m hiring mostly in Europe and I´ve been observing that most providers list themselves as taller than they are (at least 1-2 inches). It just becomes obvious when you meet in person and suddenly I have to lower my head to kiss Mr. 180cm. And on at least one occasion, I definitely met a 180cm who was way shorter than me (maybe hitting my 170cm mark) and more effeminate than his photos would lead you to believe - at which point you just say, fine let´s see if I can top and he can bottom.
Curious what your stats are on this? How much number padding do you see? And how much number padding is ok?
