Yes, I do have a preferred body type for both male and females.
I really like tall men, and "broad" men. Not necessarily extremely muscular, but someone who has a nice build to him. My boyfriend is 6'5 and I'm 5'3. So I like tall guys. I like all hair colors and eye colors. I tend to like distinguished features on men. My boyfriend has a strong, almost large nose, and I really love that.
Gaspard Ulliel is my definition of perfection in men. And lately he's gotten more and more muscular and built. His large neck and pouty lips with intense eyes are the killer.
I also REALLY love guys who have tattoos and piercings. I've always thought "bad boys" were insanely hot.
For girls, I really like curvier girls. I'm a boob person. I'm all about beautiful faces too. I prefer brunettes over blondes and I love green or blue eyes. I like girls who are close to my height, anywhere from 5'2 to 5'8.
