PC culture played a part. I just saw an old photo of kids involved in the Powder Puff football game from 1989. The guys would dress as cheerleaders and stuff their tops with balloons to simulate boobs and the girls would wear football pads and uniforms. Was a lot of fun and allowed both sexes to laugh at each other and maybe get to know each other better. Now we cant do it because we might offend so low IQ fuck up who cant tell if he has a penis or vagina
