I seem to have the opposite problem. I have romantic love for others but no sexual interest unless I am really enamored with the person. Romantic interest is more safe to me than sexual attraction. Yes I believe very much in romantic love and I have to have this first before any sexual attraction. Maybe try a wait and see approach with someone and not let the sex come before you feel a smitten feeling first. I don't know if I helped at all but I hope you will keep hope in romance. Best wishes.
