It appears that there are two definitions of "heteroflexible" afoot. I'm curious which kind DP might be.
Definition: A heteroflexible is a person who is straight but has a queer sensibility. They usually have lots of gay friends, identify with gay and lesbian culture and work for gay and lesbian rights.
An alternate definition of heteroflexible is heterosexually-identified person who is not opposed to having a same-sex experience.
