One of the largest things I look for is the absence of male genitalia.
That is a big one for me.
No pun intended.
Trista, if those are really pics of you, you're pretty hot.
As for jiggly vs not: I prefer a bit of both on a girl, to be honest. I like a jiggly bottom and REAL boobs (that have some heft), but not jiggly arms/legs.
Girls with a little belly on 'em are sexy as hell.
It's all about proportion, and what feels nice (IMO).
