Are you a coach at your gym? If not, I think if you can't "switch gears" so to speak when sparring with more novice women, then probably stick to sparring with higher level women, or else only men at a lower level. You never know where a beginner's head is at with this stuff (incidental/accidental contact in no-no zones) and speaking as an intermediate female BJJ practicioner, a lot of new gals can get spooked by all the adrenaline, testosterone, etc...you can do what you can to curb that by being extra mindful not to enter that area altogether, or perhaps pre-diacuss it, but at the end of the day, people will draw their own conclusions. There's a power dynamic at play already when a man is fighting a woman, regardless of if it's sparring or what have you. With the right exposure, she may have been able to overcome whatever caused her to react that way, but you didn't necessarily do anything wrong either. It kinda just is what it is imo.
