My husband and I have been together since 1986, married since 1992. Our sex life was really good. But starting around five years ago, he started saying that at the point of orgasm, his desire turns into dislike, not exactly disgust, but he’s turned off, and feels no satisfaction. Rather than orgasm being the most pleasurable moment for him, he ends up losing all desire. He has no erectile dysfunction and achieves orgasm. He works hard and is usually under a lot of stress. He has smoked for most of his life. He’s now nearing 50 and is on cholesterol medication. But the problem began before starting the medication. Can you explain this? Is it aging?
