Above and beyond all else? Self confidence/self assurance combined with a warm, approchable personality. Those are my absolute prime requisites. The hottest supermodel in the world, lacking those qualities, would never get beyond the first date with me.
That’s not everything, however. A strong sense of play, and a strong interest in playing with me are necessary. If a girl doesn’t want to be around me, she loses a huge amount of appeal. Who wants to waste time with someone that doesn’t like you? Not me! If she’s not up for goofing around (and I don’t just mean sex, either!), she loses a lot of appeal. No ice bitches for me - I want someone who can get real, and have a good time. Beyond that, I’d ask that she not be grossly overweight, nor unhealthy through self-neglect. She needn’t be svelt, and health concerns that are being actively managed don’t bother me.
Oh, and clean. Poor personal hygene will send me running.
Beyond that, I’m pretty much open to a wide range of female attributes. I prefer long hair, but short can be very nice too. I like small, well-formed breasts on tall, slender, athletic women, but large breasts (provided they’re not freakishly large) are fun, and there’s a lot to be said for a petite woman, too. Slender and athletic is great, but at times, I’ve found women that are more than a little soft and somewhat zaftig to be supremely hot - It’s all in how whatever the ‘total package’ might be is delivered.
I fell in love with a broad-shouldered, large-chested, muscular woman, despite my usual proclivities. She’s no super model, and she’s let herself go soft over time, but by God, she fires my engines! Her body will never be found in any magazine, but it gets me hot-n-bothered anyway, because it’s hers - It comes attached to her mind and soul, and that’s plenty damned sexy for this guy.
