@Render in the older texts, he had concubines, but I strongly believed that was like how Barbossa in PotC always kept fresh fruit on board the Black Pearl despite his curse...being emersed in the Dark Side would typically make Sith Lords less interested in sexual relationships in general, but I think he kept concubines as a way of overcompensating. That said, he was not beyond using the Force to create situations where other people did it. His most powerful ability was mind control, after all.
@Render interestingly, Leia's character growth in the old texts is far superior for feminism than whatever Disney came up with. She had to come to terms with her lineage. She married this rugged smuggler who wagered his most important possession -the Falcon- and won a planet for her and the Alderaanian survivors when she had a Prince with a whole consortium of 60 planets vying for her. She became an extremely powerful politician and her acceptance of who her father was is what defeated Thrawn.
