I'm an introvert and am attracted to introverted guys. When I think of extraverts, I think of the loud, obnoxious "I'm all that" types and that's a major turn off, in anyone.
I'm attracted to guys that are smart, share similar interests, and/or can make me laugh. It's also a real turn on when they lay it on thick. lol
I like a guy that can have fun and has some sense of adventure. I'm a Sagittarius, and I don't like to sit around never do anything fun.
Physically, I've always been an eyes, lips and hair girl. If a guy's got great eyes, lips and hair, it makes the rest of him just as hot regardless of body type.
I'd like to have someone romantic & affectionate too. Being emotionally distant is a huge turn off and stressful to have to put up with.
Honesty is a definate must, of course.
