I know someone who is demisexual, and i can definitely relate since both my ex and i feels that, cant have sex with anyone before falling in love... It just feels off...
He's also grey romantic which is another way of saying can only: A gray-romantic (grey-romantic) is a person with a romantic orientation that is somewhere between aromantic and romantic.
For example, a gray-romantic may:
Experience romantic attraction but not very often.
Experience romantic attraction, but not desire romantic relationships.
Desire relationships which are not quite platonic and not quite romantic.
One type of gray-romantic is called demiromantic. Demiromantics do not experience primary romantic attraction for a person, but are capable of experiencing secondary romantic attraction after forming an emotional connection.
Gray-romantics may also prefix a gender orientation to the label, as in "Gray-heteroromantic".
