I don't do relationships, but
if I were to hypothesize:
1) On her path- Not another high-school drop out who does child services at tafe (no offence) or hairdressing. Has at least some conceptual goal/vision of herself in a chosen field. This generally requires Intelligence. I'm not overly concerned with her having a super IQ, but a girl who is broad minded, intuitively intelligent and mature (particularly in conversations) and holds a vast general knowledge on current issues (so we can talk) interests me. I get attracted to someone outside the social matrix, an ego observer, with clearly defined values who could give a substantial answer to the question
"who are you?"
2) On this, I like a well developed EQ. A girl that just 'gets' social interactions (at least to an extent) like myself. Largely unreactive to criticism (despite the fact that girls are biologically more emotional, a partial amount of this is needed- after all she is FEMALE). Presumption of day-to-day happiness as opposed to the day-to-day my life is shit, I'm depressed rubbish
3) I only like extroverts- your "drama" student persona would be a good generalisation. Doesn't care what others think, bubbly, loud (but because its who they are, as opposed to attention-seeking), into quirky things like impersonating voices, playing music, late night coffee in a noir-themed jazz bar, Seinfeld sense of humour (and eager observational humorist herself)
4) Moves around- so plays some kind of sport/regularly exercises (hopefully a surfer, but not necessary)
5) Very sexual...enough said (not a virgin)
Yea so her personality is bright, quirky and just completely unique-
Looks wise:
Too hard to generalise. Not into the standard "pornstar blonde". Would obviously be thin, straight/white teeth, impeccable hygiene, just generally hot (very feminine) face etc?
Other then that, all hair colours/skin colours (bar very dark IMO) can be hot, so yea, individual basis.
I'm not that picky...
Actually, in summary,
Lara Croft. I like the whole action-heroine, kick-ass, rich chick with a hot British accent.
