Androflexible

Androflex is a term for a person who is mostly attracted to men but very occasionally feels attraction toward women or other genders.

History
The term androflexible seemed to have first appeared on whisper.sh by user Bucyrus. They said in their post "I decided to take the word heteroflexible one step further: Androflexible. The first word means straight but if i fall in love with same gender, then so be it. The second word means im attracted to males, but if i fall in love with any other gender, then so be it."
