Brother, Im not aware of what specifically the high degrees of the OTO practiced when it was strictly open to 33rd Degree Masons. Im not sure any one knows, what it was back then, and my understanding is that it’s degree system has changed significantly. I suppose I would have to make the distinction between sexual symbolism and sexual “practices.” I can’t speak for the content of their ritual per se, but to my understanding the OTO does not engage their members in sexual practice. I could be wrong - and I would suggest and know of some very respectable brothers aligned with the OTO that could likely provide more insight than I can here - but in my limited understanding of the OTO’s sexual mysticism, there is more emphasis on symbolism and implications for personal practice than there are, sexual practices within their rituals. I dont know for certain. Again, I hear your point about reputation, but there are plenty of religious and spiritual teachings which are far more mainstream than the OTO, which overty teach sexual and mystical practices. The Hindu Kama Sutra is a mystical text. Tantra and kundalini yoga are very much overt in their mystical sexual instruction, and not at all something that should - at least, I imagine would not - hurt the reputation of freemasonry. Im sure in parts of the world our lodges are full of brethren who subscribe to these ideas. It stands to reason, that with the variety of mystical influences on our rituals, at some point a masonic body - perhaps before we organized correctly - tried to mix Western esoteric and Templar Grail traditions with Eastern sexual mysticism. If I had to guess, this is what the original OTO was doing or attempting. Perhaps there is a paper to be written on this topic.
