I agree completely.
I used to work in a country house hotel (phwoar!) and one of the headwaitresses there was soo sexy I just wanted to grab her and hump her leg or something. She wasn't physically attractive; a fairly plain face and thinner than my tastes dictate, but she had such a great personality that it was impossible not to find her sexy. And it wasn't because she was sluttish or anything, twas because she was always happy, always smiling, and always giving everyone around her good vibes and energy. She was just a totally great person to be around. One of those people that can make you feel good about yourself just by being in her prescence. That's what made her sexy, not her looks or body.
