how much do you think male genetics has to do with this? maybe certain body types tend to be more attracted to each other and that could explain the difference?

for reference, i'm 6'3, longish limbs, ecto-meso type build, no fatties in my family male or female. also most people in my family engage in some type of working out/exercise and i've been exposed to that for a long time, but that's probably more of a sociological influence.

thoughts?
