Or: sexuality exists on a spectrum, and many people tend towards the poles because of cultural and social pressures. For instance, everyone thinks I'm straight because I'm married to a woman. Bisexual erasure is probably a big problem in sorting out how attraction to the same sex can be passed on genetically.
