Sextard 

Sexual Retard; Homosexual, either male or female. Someone who has not developed enough sexually to enjoy sex with a partner of the opposite sex. Something wrong, sexually, that causes a man to place his penis inside another man's butt, or vis versa. Sextarded women are lesbians who have been raped or haven't completely developed sexually, thus causing them to only have sexual relations with women or girls.

Suzie can give good head if she concentrates, but she's really a sextarded lesbian who would rather be lick'n twat.
