I have discovered over the years that I like blondes. There's something about that light-colored hair... it makes them look like this golden purity of beauty.
Also, I like female redheads.
Large warm hands in males.
Silky straight hair and stunning blue eyes.
A large muscular body that is durable, because I tend to be aggressive when I express my affection. (I tend to punch and hit people I like.) Yes, even for females. But not too muscular in their case, so much as more robust and taller than I am. I always want to be the smallest one.
Feminine facial features. A soft face, little body hair. For both males and females.
Frilly outfits. Frilly skirts. Flowers in lady's hairs. Actually, my own sense of style is pretty much my turn-ons. I wear outfits that I find appealing on women.
Here's a recent one I discovered that is a really big one: Scientists, glasses, librarians, doctors. Both genders. You get many points if you have a labcoat and glasses. This only applies to these specific nerdy accessories though. I don't like people who have unhealthy pale skin and stereotypical nerdy physiques of being underweight (or overweight).
Generally though, I'm not really all that attracted to realistic humans. I find anime-styled humans and anthropomorphic creatures to be most attractive. Sadly, our reality can't look like that though. But those are the physical features that stand out in this reality. (If it's anime-styled though, then HUGE bonus points.)
Oh and let us not forget sounds! I am a very audio-oriented person. Sounds affect my mood. So I like a nice, smooth voice. Deep male voices especially. And British accents get a bonus. Something that just slithers into my ear and comforts me. A romantic tone of voice especially.
As for personality, I don't really get any turn on from it. I just want someone who isn't overly mean, is kind and gentle, shares my interests, and understands me. Someone who can be my best friend.
