I find it difficult to believe that Bill and Hillary have been intimate any time lately. Years, maybe decades.
I don’t think they ever have been. Strictly a political marriage from the outset. She needed a husband to advance politically, he needed a wife to advance politically. Neither was interested in monogamous marriage, or in each other, sexually. But, they saw promise in joining forces politically. So, they did. And each has gone their own way, sexually, ever since.
