Interesting question.

As a young college age male (19) I am attracted to women with body types that are well proportioned and by the Original Poster's definition athletic. I do not like extremes of anything in the looks department. Curves or large breasts on a woman often come with the addition of a high body fat percentage.

High body fat can lead to things like diabetes and heart disease. Those genes can be passed on to children that could result from a coupling with such a person. Health is a concern for me and as someone who works very hard to maintain their own physical health through diet (which isn't always easy) and working out I'd like someone who had the same priorities.

While body type is just one factor in my evaluation of a woman of woman that would be my ideal would be as follows:

A) 18% or Less Body Fat (weight is somewhat subjective due to height).

B) An overall height of not less than five feet two inches and not greater than six feet (past six feet three to five inch heels would be a problem).

C) Good overall healthy appeareance. Good hygene, Good teeth, Healthy skin.
