It's not that it's an obsession, it's just a fundamental truth that masculine and feminine principles aren't just embodied in man, but in all creatures, nature, the universe, etc. You just don't like the idea of anything sexual being studied by a group of people who wish to explore those ideas.
But you should understand, because of that underlying hatred by people like you, you are the exact reason these societies are so secret! BTW "occult rituals" just means secret rituals, secret because of ignorant idiots with hangups about sexuality.
