There are many things ladies do (IRL) that can be utilized when playing a female. Pay attention to how ladies behave and you will pick up on small things that will make you think how you missed on these.

Few examples:
Men bow; but women courtsey
Men laugh, lol or rofl; women giggle
Men strut and be proud; women blush
Men wear clothings that are awesome with stats; women tend to wear clothings as they look good
Men tend to boost; women usually try to minimise the effect and at times tell others they did good than to take all the credit
Men can be like Dupmasione (Eternally Horny Elves); Women often whisper amoung themselves about the people they like
Men love all good looking women and flirt with them; Women will blush if she likes the guy or avoid men whom they don't like
Women usually do not belch or burp
You have to be classy to play a woman (good or evil)

Some of the men and ladies will not agree with these observations I had of us ladies, but its not true at all times.
