Looking at Hijiri porn reminds me of a question, is virginity required of Buddhist monks as well? I hear it's not the case with shrine maidens in Japan despite common misconception, so I started wondering.

Like Shinto, there are so many sects and divisions of Buddhism and rules differ for each of them. They run the gamut from totally rejecting sexual activity to encouraging and pursuing carnality. Marriage is allowed in Japan, but Hijiri also comes from a time when the vow of celibacy was serious. Of course, she's already a lapsed Buddhist since she broke a bunch of the rules anyway.
