as a 40 year old man...here are my thoughts....
women are God's greatest gift to man. no one can make me as happy as my wife, or as sad, or as upset. i do not believe that we should be more like each other. men should be men, and women women. whatever that definition is to each person. it is not an unusual day in my house for me to be cooking and her to be outside in the garden. my wife and i are very different, and that is what makes us strong. it is the differences that bring new experiences and variety into life.
as far as sizes, i do think that finding each other attractive is important. i think it is equally important for me to find my wife sexy, as it is for her to find me sexy. and that means telling each other how you feel.
it is not fair to change over time and be surprised that the change "changes" how others see us.
anyway, i am grateful for the frienships, love, and time spent with every woman in my life.
