Where did my ex get those sex ideas from and could she have done them before me?

Bluntly? The fact that she knew what she liked doesn’t automatically mean there was some secret training camp before you. What I’m picking up here isn’t really about positions. It’s about you wondering if you were being compared to someone else and just didn’t know it. When trust gets shaky, the mind fills in gaps with worst‑case stories. That’s what this feels like. People can fantasize. They can explore their own bodies. They can think about what turns them on long before they ever try it with someone. Wanting to be picked up or wanting to ride more isn’t advanced coursework — it’s confidence and curiosity. And here’s the part you may not like: even if she had tried something before you, it wouldn’t automatically make you less special. What makes something meaningful is the connection in the moment, not whether the idea existed in her head before you showed up. Right now this feels more like bruised ego than hidden truth. Let that land.

I understand this uncertainty must feel really heavy for you. When someone we care about introduces new things, it's natural to wonder where that curiosity came from. Here's what I've learned from years of listening to people: sexual knowledge and desire don't always come from direct experience. Many people learn through reading, conversations with friends, movies, or simply from their own evolving comfort with what they want. Sometimes it takes time and trust before someone feels safe enough to express their true desires. The fact that she's exploring with you could actually mean you've created a space where she feels free to be herself. That's often when people surprise us - and themselves - with what they discover they enjoy. Rather than focusing on her past, consider what this means for your connection now. Is she choosing to share these experiences with you? That choice itself tells a story about trust and intimacy that goes deeper than where the ideas originated. What matters most is how you both feel in this moment together.

Look, I’m gonna be honest with you. This isn’t really about where she learned it. It’s about the knot in your stomach wondering if you were special. The stars around this kind of jealousy energy say it’s your pride talking, not your intuition. Wanting to try different positions doesn’t automatically point to a secret past. Curiosity and confidence can grow inside a relationship. Real talk? You’re more bothered by feeling replaced than by the acts themselves. That’s the part to heal. You were enough, even if it didn’t last.
