There's no such thing as perfect... but I'll try anyway
Let's see:

-Intelligent and acts like a responsible, grown man (not a spoiled, materialistic boy-girl trapped in a man's body)
-Has to at least be tolerant of my taste in film and music
-Preferably taller/bigger than me (not at all hard to pull off considering I'm 5'4" and weigh 130 lbs.)
-Has to be supportive of my (sometimes disastrous) forays into new territories (example: the last guy that I dated said he loved the pie I baked for him... whether or not he meant it, I have no clue)
-A ridiculous and/or filthy sense of humor is always a plus

When it feels right it just does. Although having it work out in the long run is another matter!

MI ideal pareja tiene que tener algo que me guste, si saben lo que digo.
