Exploring Boundaries with My Partner

I’ve been open about my kinks since being in a committed relationship, but my partner isn’t interested in one specific aspect, roleplay involving CNC themes. We talked extensively about boundaries and comfort levels; I understand her limits are important. But last weekend, during what was supposed to be another typical date night out with friends, an urge hit me hard, a moment where it felt impossible not to act on that fantasy for a fleeting second. Of course, nothing happened in reality. Still, I’m left analyzing why this one aspect feels so pressing. How do you reconcile understanding your own desires when they clash with what your partner is comfortable with?
