ego = low self esteem

we always associate the word ego wf guys ie "the Male Ego"
but what about females who are also egoistic?
haven't got a word for that i think.

so does this mean that the female equivalent of ego would better be describe as "low self esteem"?
after all these 2 words seem quite similar in many ways.
in fact, its just a difference of a thin line.

so ego for female = low self esteem?
set.

now to find a male equivalent of a "slut".
