Why Knowing Every Sexual Detail About an Affair Can Delay Your Healing

After infidelity, it is natural to want to know everything. Many betrayed partners feel like they cannot rest until every question is answered, every gap is filled, and every secret is exposed. It is understandable because you are trying to make sense of something that shattered your world, and knowing every detail can feel like the only way to take back control.

But when it comes to sexual details, such as exactly what they did, how they did it, what was said, what positions, or what they enjoyed... those answers almost always bring more pain than peace. I know it may not feel that way now, but I want to explain why most therapists, researchers, and affair recovery experts, myself included, strongly advise against digging into every explicit detail. Here is why.

1. Those details fuel intrusive thoughts and images.

Once you know specific sexual acts, your brain tends to replay them like a movie you cannot turn off. These mental images can pop up at the worst times, such as when you are trying to sleep, be intimate, work, or even just get through the day. They become stuck loops, making it harder to calm your mind or focus on healing.

2. They intensify PTSD symptoms.

For many betrayed partners, the discovery of an affair feels like trauma. Learning vivid sexual details acts like a “trauma anchor,” deepening symptoms like flashbacks, nightmares, emotional reactivity, and hypervigilance. Instead of helping you feel more in control, the details often keep you in a heightened state of pain and shock.

3. They trigger painful comparisons.

Once you know exactly what happened, it is almost impossible not to compare yourself to the affair partner. You might wonder if they were prettier, more exciting, or better in bed, even if those things are not true. These comparisons can devastate your self-esteem and feed false beliefs that the affair happened because of something lacking in you.

4. They deepen emotional injury rather than bringing closure.

Many people believe that if they “just know everything,” the pain will stop. Unfortunately, sexual details rarely bring closure. They usually add new layers of hurt, humiliation, and disgust, which can make forgiveness and trust-building feel even further away.

5. They prolong your emotional recovery.

Even long after the conversation is over, the details stick. Months or even years later, a word, a touch, or a place can trigger those mental images again. Instead of helping you move forward, the information often keeps you emotionally tethered to the affair.

6. They can damage intimacy in your relationship.

Rebuilding sexual connection after betrayal is already hard. Knowing every explicit act can make it harder still, because certain images or acts might bring up flashbacks or painful associations during moments of closeness with your partner.

7. They give the affair partner more power in your mind.

Every detail you know can make the other person feel like a permanent third presence in your marriage. Instead of fading into the past, they can take up more space in your mind, making it harder for you to feel safe and connected in your relationship again.

8. They cause enormous suffering without meaningful benefit.

Most importantly, sexual specifics do not usually change anything about how you heal or what decisions you make about your relationship. They do not explain why the affair happened, what your partner was feeling, or what needs to change going forward. They mostly just create more pain.

Wanting to know everything does not mean there is something wrong with you. It means you are trying to regain control after an experience that felt wildly out of your control. But in most cases, those sexual details do not bring the comfort or closure we are hoping for. Instead, they tend to keep the pain alive and stall healing.

If you feel like you cannot rest until you have answers, try focusing instead on the emotional truth of the affair. Ask questions like why it happened, what your partner felt, and what they are willing to do to help you feel safe and rebuild your connection. Those answers tend to bring more relief than the ones about what positions they used or what they said in bed.

If you feel tortured by the constant urge to know every detail, or if these thoughts are keeping you stuck in a painful loop, please consider pursuing trauma-focused therapy. Approaches like EMDR (Eye Movement Desensitization and Reprocessing) or somatic experiencing can help calm the nervous system, reduce intrusive thoughts, and release the pain that feels trapped in your body and mind. Healing really is possible, even if you never know every sexual detail.
