A Night of Extreme Fantasy Roleplay

I was in my early twenties when I found myself drawn to an extreme form of roleplay that involved a dominating and submissive dynamic. One night, after months of mental preparation and researching safe practices online, I met someone equally interested and experienced. We agreed on strict safety measures and signals before the act. She dominated me with such intensity that every command was clear and sharp. Her control over me was absolute; she forced me into positions I had only imagined, pushing my limits but staying within our pre-agreed boundaries. The experience left me emotionally spent yet intellectually stimulated. Is this kind of intense roleplay common among others who explore BDSM? How do you find partners willing to engage in such an intimate and complex activity?
