[M4F] Can you pinpoint to where/when/how your biggest kink started? If so, what happened?

What is your biggest kink and where did it come from? Is there a specific moment or experience that you can point to and say that's where it originated? I'd love to talk about your stories, and I'd be happy to share mine.

I'd also be interested in discussing how your kinks have evolved over time, or if you've had any instances of one only lasting a short time, or only with a specific partner.
