Crossed Boundaries Need Clarity

I (28F) recently faced an uncomfortable situation with my partner (29M) where he disregarded my boundaries during an intimate moment. This has left me feeling confused and hurt about our relationship dynamic. I want to address this but don't know how to start the conversation without causing conflict. How should I approach this to ensure understanding and respect moving forward? Any advice? #SurvivorSupport #HealthyBoundaries #RelationshipAdvice
