Hm well speaking for myself, I don't have a set specific type of guy I like. I may be partial to dark hair but I think lighter hair looks great too. Eye color is not a big deal either. Neither is his race. So for the most part, I feel I don't have a set specific in terms of all around traits as I find somethng attractive in all.
However... The only thing I realized I wasn't really into was overweight/fat. As much as it pains me to say, I just can't get physically attracted. The first guy I ever had light play with (I say light because we didn't do much) was overweight and I was very turned off physically by his huge belly... I know it sounds shallow but I have to be honest. After that experience, I did try again with another bigger fellow and the same result happened. It was then that I knew I just was not attracted to that trait...
So for that reason, I wouldn't want to get into a deep relationship with an overweight guy because I wouldn't want to put him in that awful situation of not having 100% of attraction. He would deserve someone who wanted all of him and it's nice because there are lots of guys who would be into them over any other type.
But yeah, other than that, I never really thought about this particular topic because I'm already pretty open to all sorts of colors and races and styles.
