I do wonder sometimes if what I like is too specific/stringent. It isn't even in services provided (my tastes there are pretty vanilla), but rather in the way someone looks. But it does seem to lead to people I'd actually find attractive, so I'm not sure there's any way around it.
I like British (or other native-English-speaking, like Aussies, Kiwis, Canucks or Yanks), late 20s to late 30s, size 10-12, preferably natural breasts (and not that bothered as long as they're not huge/saggy), shapely legs (not stick-thin) and most importantly a round arse (meaning not a flat one, not "tight" or "toned" but otherwise small). That last one seems to be the deal-breaker time and again, there just aren't that many women with arses I find attractive - that goes for civvy life too. They're too often flat and shapeless, or too far the other way, fat and shapeless. I like it defined and grab-able, definitely standing out from the countour of the back and thigh.
Am I chasing a unicorn here? Does anyone else do this?
