My "type" has changed over the years.
"When I was younger": Blonde, Caucasian, large booty, large boobs, medium weight. At the risk I might be dating myself, we are talking about "natural" blondes. Back then, hair dyeing wasn't as common nowadays.
"A decade or so ago": Caucasian, Latina or black, close to pretty much non-Asian. Didn't mind body size as much. In a way, started to move away from pure wild sex. It is at the later stage where I started to get myself into Asians...
"Nowadays?": As mentioned by hornygandalf, what's more important is the organ between the ears. But into the more physical side, I am now more into Asians, smaller boobs and ass.
