I tend to prefer younger partners, or people who look younger than their age.
For porn and "fantasy" I'm extremely visually picky..real life a tad less so, as chemistry personality do contribute some.
Sporty/fit girls (true fit not "average to chunky" body, as so many who claim to be fit are) the make up and high heels look is great for special nights out, but if 2 hours are spent daily putting on the face before even leaving the house to pick up eggs..not so attractive. There are variances and such of course.
For guys the range goes from cute ripped muscle boys (like underwear models) to slightly fem twink types. Mildly androgynous also seems to be a factor.
I also am attracted to brainy types. I enjoy intelligent conversation, and hate to repeat myself, and while I love imparting wisdom or information, having to explain everything can be a drag.
I'm pretty well fucked eh?
