I have an assassin like that... gets close to her target and then takes them out.
I have a number of female characters - in some circumstances they simply fit the role better than male characters. For example, my thief character is a female. She earns the trust of her victims, to the point where they'll let her into their homes. Then she'll rob them blind.
And as CCNA said, the best clothing mods out there are for females (although this only applies to me in Oblivion).
My characters could never be so slick. Very naive and likely to be on the other end of such a predicament (Providing the person would even think to lure a woman as she does to men)
