I know I could be reading stuff into it, but to me that whole blog post sounds a lot like someone who spent a lot of time emotionally adrift and has come up with a house-of-cards series of justifications to cement some kind of coherent self-identity.
"Gay with a chance of spiritual ladybits" is a much simpler explanation than "I lean much, much more strongly to towards men than women, but my wife, who is my spiritual-soul-mate-partner-best-friend, fulfills just enough of my human need for close emotional companionship that she is the one woman to whom I am genuinely physically attracted and so maybe sexuality is far more a complicated spectrum of emotional and physical needs than anything else and labels suck".
