Boreasexuality is an orientation in which one has an exception to one's normal orientation, that typically revolves around one person in particular. For example, if someone who identifies as gay feels attraction to someone of a different gender, in that case it may be described as boreasexual towards that person.[1][2]
Someone who is boreasexual may also identify heteroflexible, homofexible, ceteroflexible, or biflexible but that is not a requirement.
