look up any word, like cleveland steamer:
 
1.
Sexually attracted to two or more "genders." Used instead of bisexual.
I walked in on Zack there and he was diddling a guy, two girls, and a trannie. Man, that's one flexual mofo.

My girlfriend was so flexual last night, she showed me knew moves I didn't think she knew. I'm a happy guy...
