Bisexual
A person that likes both males, females, and sometimes some other genders. A bisexual female is not "only doing it for men." Bisexuals are not "just confused." About their sexuality. They are not more likely to cheat. Finally, although they like more then one gender does not mean they don't have standards.
"I like John but Sally is also looking pretty shmexy"
"Bisexuals are real and valid"
