The actual reason is because the church was protecting its assets from the priests. Back then, priests were very powerful members of local government and controlled a large percentage of the wealth in an area. If they could get married and had kids, their kids would inherit the wealth they accumulated instead of that wealth going to the church.
My highschool job was working at a sporting goods store. My closing duties each night were to clean the women’s restroom and occasionally cover for another department to clean the men’s room. I can tell you that the women’s restroom was always grosser. Yeah, there would be more pee on the seats and floor in the men’s room, but the rest of the place was far cleaner than the women’s.
