What if Hanzo got prostate exams so often he unintentially gets trained to get turned on by the sound of latex gloves and the noise of the lube coming out of the bottle (like the spittling noise when theres not much left at the bottom of the tube)

he’s so conditioned to it. just like a well-trained puppy; he hears latex gloves snap on and his hips instantly become loose and warm with the need to bend over and present. When D.Va tries getting the last bit of ketchup out of the bottle he has the most obnoxious, needy boner because it sounds like the lube.
