I second the suggestion to investigate cupio- and fictoromantic microlabels. If demiromantic doesn't feel right you might find something else you relate to amongst the different greyromantic identities. At the end of the day the labels just facilitate our understanding of ourselves and our ability to communicate our feelings to others. If you're not sure it's ok to just be questioning for a while.

It's possible to desire romantic relationships and enjoy romantic stories without experiencing romantic attraction to specific real-life individuals. You could also be experiencing a degree of romance or sensual repulsion, some or all of the time. Personally I love the idea of my romantic relationships, but sometimes I find it nauseating to act them out with kisses and "I love yous". It's like there's a disconnect between what I wish I felt and how I actually feel. For me that feeling comes and goes.

Try to observe what you're actually feeling - do you experience romantic attraction to the people you go on dates with? What is your motivation for going on dates? Have you ever had a crush? How did you know when it became a crush? If you find that you do experience attraction after developing a bond or friendship, that's demiromantic. Otherwise you could be elsewhere in the greyromantic camp or even fully aro. I have heard of aros with "romantic personalities", they do exist.
