BW, while you may not feel lean, you certainly are. (Just like I know I am lean, but to me it is not lean ENOUGH for me personally).
Just a few facts re bodyfat (BF) from ACSM (2005):
Essential BF: 3-5% (Male), 8-12% (Female)
Elite Athlete BF: 5-10% (Male), 12-15% (Female)
Average BF: 15% (Male), 25.1% (Female)
Even if a female has the SAME sum of 6 (or 8) skinfolds (SF) as a male, she will be a HIGHER BF% (due to the higher essential BF needs, etc.) However, generally speaking, whatever a female is in BF%, if she were a male she would be ~3% BF LESS. So, technically, a female at 10% BF is the 'same' as a male at 7% BF (and a female with the SAME sum of SF as a male is LEANER than he is!
