As Alexander pointed out, there is a correlation between Age and your chance of being a Top or a Bottom. ┬áThe chart above shows the relation between Age, Height and Weight to top/bottom-ness. ┬áThe dotted line is “Average,” so if a bar is below the line there are more bottoms in that group, and if the bar is above the line there are more tops.

  • Younger folk are more likely to be Bottoms
  • After 36, the chance you’re a Top increases yearly…until you’re 60.
  • Men under 5'10" or over 6'4" are more likely to be Bottoms.
  • Guys lighter than 180lbs or heavier than 280lbs are more likely to be Bottoms.

Any ideas why guys over a certain size start trending more bottom-ish?
