It's sort of funny, but most of what I find attractive is whatever I see in my partner. I identify people better by the way they walk and fill space and their bodies and hair and so on, and it's hard for me to picture his face. I can think of individual features sort of fuzzily though. It helps to look at a picture.
He's 5'7" or 8" I think (doesn't really matter to me) and is slender and wiry.
He has long, dark brown hair in a ponytail and it is perfectly, loosely curled and looks like a freaking shampoo advertisement. It's so effing soft and volume-y. Can't emphasize that enough.
He has olive skin and big bambi eyes and the longest eyelashes I've ever seen.
Soft skin is really important, but honestly if it was all burned off or if he turned into a crocodile I would still love him and take care of him. It's weird, because I hate feet, but his are absurdly soft on the bottom, and he doesn't even own skin maintenance products.
His nose is very nice. Sort of patrician.
His lips are insane. Super soft and plush.
His eyebrows are asymmetrical and rather generously filled out. They fit him.
I don't like when he doesn't shave, because it's super scratchy on my face... I would be scared if he had a lot of non-ear piercings because they might get caught on things. I have to prompt him to shower and brush his teeth at times, which isn't that great, but fortunately he has very cavity-resistant teeth. It'll improve as he grows up.
I think cleanliness is very attractive.
Also, I hate to point it out because it's something that's hard to control, but I wouldn't touch his face much if he had acne (he doesn't), because that would just irritate his skin and squick me out.
