Which Are the Correct Classification of my Novels?

I write novels set in times past. I agonise over how to describe them. The hero and heroine are imaginary but they are not 21st century people dressed in costume. The novels  are romances enriched with historical facts and  social history. My hero and heroine's bedroom door is never wide open. So, how should I describe my books? Are the historical novels, historical romances or romantic historicals? And which term is the best to describe them - traditional, sweet or clean? I want to send a clear message to potential readers.
