My Weekend Secret

I'm in a long-term relationship but this weekend, I met a stranger at a bar. We talked for hours, exchanged numbers, and agreed to a brief fling if our schedules aligned. They did. The sex was intense, raw, unlike anything with my partner. Afterwards, I felt conflicted, exhilarated by the freedom yet guilty over betraying trust. Why do I crave this kind of risky connection? What does it mean about me?
