In regards to penis vs. vagina - that is sex, not gender.

In regards to masculine vs. femininity - that is gender.

masculine and feminine traits are different in many cultures. i'm sure there are biological aspects to it, but social influence is probably the most considerable. it really comes down to that men and women are more the same than different- we are the same species after all.

you could describe masculine as physically dominant. this has nothing to do with the sex of the person though- if you gave women treatment with testosterone they'd be just as strong physically as men, etc.

what is defined as masculine and feminine are generally only opinions, really.

there are most definitely differences, but if they're a result of social influence that means they're changable. for instance girls learn to read better at a younger age than boys do. BUT, both boys and girls are taught to read at the same time. that time just happens to be closer to the time that girls are more likely to be able to learn the material faster/better- leaving the guys in the dust. the result? on average, though only slightly, women score higher in literacy than men.

all the same men on average, score slightly higher in math and spatial skills than woman do.

it's also known that men and women use different portions of their brain for different things, yet we obviously function very similarly.

personally though... i'd define femininity as overly emotional, dramatic, sociable, caring, etc.... and masculinity as corageous, controlling, etc.

don't forget though, whether man or woman, each person is an individual and has their own specific cardinal and seconday personality traits.

oh yeah, reference, 'Psychology' text book by hockenbury and hockenbury [5th edition... i think] none of that is quote, but it's in there saying the same thing more or less.
