My physical preference is for the appearance of my own ethnicity (or those that look like us) but physical preference is not what I go by or dictate who I desire. However, you are asking for physical ideal here so that is what I am going to say. I am bisexual so shall list both:
Women: I love them to fit under my chin. I do not know why I like that so much but I do. I find Rroma Gypsy women the most beautiful in coloring (black hair, brown eyes, darker skin)... though eye color is unimportant. Physically, think the stereotypical “bar maid” we see in films are read of in books: buxum, curvaceous, etc. (I am certain that reality did not reflect this) Oh long hair.
Keysha does not meet my absolute physical ideal in all ways but I do not give a squirt. I would be with her no matter what she looked like. However, she is my perfect woman because, as I said, physical ideal is not my barometer of how I view a person.
Men: I really did not plan it this way but, basically, the good side of the Rroma male gene pool. Some of us are butt oogly and a lot do not age well but the good ones are great. long black hair, eye color unimportant, darker skin, my height or a bit less or a bit more, muscular (not bodybuilder)
My male love (yes, I am bisexual and, yes, I am polyamorous) just turned out that way (he is Greek with kind of a golden color to his skin) but, like with Keysha, I would not have given two squirts if he happened to be wearing another body (yes, they are great friends).
I do not like fake tans, either bottle or salon, on anyone.
I, too, prefer scars if they are earned honestly because it shows that a person has lived an active, interesting life. Each scar is a story. I got mine from normal childhood stuff, working on cars, sword and knife sparring, a fight where the wannabe robber clipped me, a couple of pox marks, and more. I am also not bothered in the least or turned off by Keysha’s surgical scars. I am not that superficial and am actually appalled when someone loses desire for their s/o due to things like surgery. To me, those are her war wounds… a battle hard fought with no certainty of her survival.
I prefer not “perfect” features because that is not interesting. Here is a perfect example.
