(besides the obvious, like compatible values and lifestyles, and sexual attraction):
-love of nature
-rational and logical
-creative, either artistic or musical
-healthy and actively trying to stay that way
-compatible sense of humor, not too serious (excessive silliness is awesome, as is humor which is dry like a desert)
-energetic, can keep up with me
-independent, financially and otherwise
-must be a fairy (It's ok if he doesn't know it yet. )
Prefer to Have:
-knows martial arts of some sort
-somewhere near the middle on I and E
-has an attitude to match mine
-not too much Fi, or S
-can't deal with an open relationship
-doesn't want kids
-the obvious, like can't have a criminal record, be abusive, into drugs, etc.
I actually made a list like this (the OP) when I was quite a lot younger, and then learned to be a lot less specific.
As far as the obvious, which is compatible lifestyles, personalities, values, physical attraction:
physical: skinny but fit (or the other way around), pretty yet masculine
lifestyles: healthy, interested in sustainability and living off the grid, likes going outside and socializing, (preferably) likes dance clubs, environmentally friendly
values: politically liberal/anarcho-socialist leaning, pagan/equivalent spirituality
physical attraction: not much else to say about it, except that it's important.
"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
