The things that really matter to me are as follows:
Things I'd notice on a first impression:
- Knows how to take care of her physique; hygiene, weight, clothing.
- Clever/intelligent /witty demeanor.
- Not afraid to retaliate verbally; sharp tongued (to a certain degree).
- Not a friggin' chav.
Long term/deeper personality;
- Friendly/sweet.
- Geeky interests in one degree or the other, I'd like to be able to relate to her and the other way around.
- Lively to one degree or another. Fact is, I need someone that gets me away from my desk.
- Have a sense of humour. I need someone to laugh with.
- Has a certain degree of enthusiasm for the things she likes. For instance, when I was at the MCM Expo 2010, I went with my niece. You could barely tell she enjoyed it, so quiet and reserved she was. I like a girl that's the opposite.
As you notice, there's little about a girl's physique, I really pay more attention to attitude and personality. I can like such a wide variety of physiques it's useless to list them all.
