The moment sex becomes something you owe rather than something you want, the dynamic shifts entirely. It reframes intimacy as a transaction, and that's where things start to go wrong. Sex debt thinking often comes from a place of insecurity or poor communication. Usually, couples have never discussed what sex actually means to them in the context of their relationship.
At any point, any of your partners may have been thinking of someone (or even something) else to help themselves get over the edge. The idea of making someone orgasm with, to put it your way, just you is an illusion. People bring a lifetime of experience to the sex they have, including ways to help facilitate orgasm. Sex alone may not be enough to get your wife to come.
The realm of intimate relationships is wide and diverse, providing endless opportunities to discover joy, pleasure and connection. But exploring new ground without consent from both parties may cause unease, betrayals of confidence and even injury. A good sexual relationship depends on this kind of conversation because it ensures that any exploration is grounded in permission and mutual curiosity, strengthening the connection and enhancing the experience for both parties.
You are being asked to play into the contorted (you might even say deluded) way that many obsess about penis size. Inflation runs especially high on apps, where (at least in the gay world) it is wise to subtract an inch (or two!) from whatever number a guy presents. Continuing the charade IRL can feel like actively thrusting yourself into absurdism. You don't have to lie to anyone for the sake of their penis-shaped ego.
