Recently, my distributor of e-books (Draft2Digital https://www.draft2digital.com/book/ ) joined services with Oyster. Most - about 90% - of my sales are through Barnes & Noble, but any new area needs to be tested. So, I signed my books in to the Oyster catalogue, to my amusement two books were excluded for being classed as Erotica, I class them as Erotic Romances. True, they are steamy, but the passion is in the story, not the story. Sexual Explosions, and The Love of the Sea were excluded, but Sex at the Mill, and A Sailor's Love were admitted. ASL is more erotically charged than its predecessor TLOS.
