Demialterous

 is an aspec (specifically altspec) orientation where one experiences alterous attraction to a person after they have developed an emotional connection to them. What counts as a "close connection" can vary between those who are demialterous. Forming an emotional bond with someone does not mean that one is automatically attracted to said person, as it just means there's now a possibility for one to feel attraction.

Some who are demialterous may choose to further define their orientation in terms of genders they are attracted to (demibialterous, demihomoalterous, etc.). Others do not find this necessary, or feel that they have enough experiences of alterous attraction to figure out who they’re attracted to.

Etymology
The prefix demi- means "half" or "partial". The prefix is also used in words such as demigod.
