In fact, most haremlit readers don’t want a lot of sex in their books. The spice has to be a payoff to a well-developed romance arc, not there for its own sake. They want to see the main character as someone who deserves to get the girls because he’s earned their affections through who he is and what he’s done, and only then should the action move to the bedroom. It’s also worth noting that readers don’t like love interests who have a lot of experience or even any at all. They prefer to see women with traditional attitudes about sex and romance, who devote themselves to the main character and never look at another man.
