There's been a lot of rhetoric going on along the wild edges of Heathenry based on the mistaken assumption that we cannot pursue primal masculinity with women present or involved, or vice versa. While I certainly am an advocate for sex-specific fellowship groups, spirit is the living essence of nature, not separate from it and we were made by nature for partnership. No great spiritual undertaking can be forged outside of natural law, it is only through surrender to the greater structures of this existence that we can then rise and thrive.
I know the word and the idea of surrender is something many believe to be antithecal to primal masculinity but that is the arrogant machismo of the lesser self childishly rebelling against the greater Self. Even Odin sacrificed his lesser self to his greater Self to win the runes. Further, while codependency is a sickness of the modern world, it's polar inverse of total independence is both equally unhealthy as well as simply not Heathen. Heathenry is inherently preservative and ancestral. None described it better than Vincent from @americanheathen in his profound "My Name is Not my Own" poem. Any group that argues against appropriate partnership argues against the essence of what it means to be Heathen.
True partnership is defined by a balance of compliment, a striving for sovereignty out of a desire to provide for one's family. This is a visceral motivation greater than any idealism and we strip ourselves of that power when we disregard it. A man who fights for the things he loves will always fight better than a man who fights because he hates. Inversely, while evolutionary theories like hypergamy explain root inclinations towards certain behaviors, to discredit the rational faculties of men or women based only on an observable instinctive drive belittles the very idea of spiritual growth. Cynically, arguments for inherent infidelity can be made for either sex. We should not flee from our base natures but neither should be succumb to them in some sort of nihilistic hedonism. As with all things, balance can be attained and I will continue to bear the torch for the virtue and necessity of complimentary partnership.
