'Outlander' by Diana Gabaldon also has elements of sexual romance. The story of Claire Randall, a married combat nurse from 1945 who is mysteriously swept back in time to 1743 Scotland, and her relationship with Jamie Fraser is full of passion, love, and yes, sexual attraction. The historical setting adds an extra layer of richness to their relationship.
One of the well - known sexual romance novels is 'Fifty Shades of Grey' by E. L. James. It tells a story about a young college graduate, Anastasia Steele, who enters into a complex and passionate relationship with a wealthy and mysterious man, Christian Grey. Their relationship involves elements of BDSM which makes it quite unique in the romance genre.
