Ok since vulcans have mating seasons (their pon farr) it means they have estrous cycles and not menstrual cycles which means that they don't have menses.
Imagine a vulcan learning for the first time that human women bleed from their vaginas for a week every month.
Just trying their best to master their emotions and be all calm, like "what a fascinating yet odd physiological phenomenon"
While inside they're like "what the fuck? What the fuck??? what the FUCK!? WHAT! THE! ACTUAL! FUCK! IS! WRONG! WITH! HUMANS!?!?"
Meanwhile a klingon would be like "BLEEDING IS THE SIGN OF A TRUE WARRIOR! THIS IS GLORIOUS!!"
The Klingon pov at the end was a glorious twist.
