Men please-Is this attractive? Should I change?

Please be completely honest. 5'4" 110lbs (summer)-120lbs (winter) athletic build/runner legs, straight med-brown waist length hair, measurements 32A-26-34. Personality sort of wannabe hippie/wannabe intellect/wannabe "Man vs Wild", positive attitude, likes to eat healthy, but not crappy food, but I can't wait for my b-day cake attitude. I want to know because I'm told my body needs improvement to hit "HOT" status. And my personality needs to be more mature, a realist, weigh 105lbs always, give up muscles & go for more "skinny" look. Cut my hair to bra line. Just be honest which is more attractive/preferred. I've been at 105lbs but I'm hungry, have loss of endurance for my active run/climb/hike lifestyle & get depressed w/ lack of endorphins. I'm told men rather the 105lbs woman, who has more of the obedient type personality & not athletic. Is this true? So, I'm curious. I like who I am, but I want to be my man's perfect woman even if it means giving up the active lifestyle. Also we've got kids so I do have stretch marks, but they don't bother me too much. Just one of those things I have. I would get it fixed but can't afford laser surgery to remove. Do stretch marks bother men? I would consider boobs like big B's for him but I like being natural. Do men not like small A boobs? Really be truthful.
