It's an interesting way to frame the concept.
I think the variations are widespread, but I wonder how and why they might cluster. I suspect that for all but the little kids who insist on their gender openly from their earliest years that any clustering is based on reaction patterns and conformity. Enforced conformity might be a larger theme for a 20-something transitioner, for example, where it was forced through adolescence, whereas reaction-based issues may predominate among older transitioners. What I DON'T believe is that intensity is necessarily any different. Rather, that a lot of things both individual and social converge to twist individuals' gendered lives into knots.
There are all kinds of psychological reaction patterns - repression, suppression, dissonance, etc. And the issues they foster are all over the place too. Depression, adjustment problems, hyper-aggression (and conversely, aversion), personality disorders, OCD, and ...
My story is mostly about suppression and to a lesser extent, dissonance. Things that fit the standard narrative for me are episodic crossdressing back to pre-school years, a preference for female friends, very strong identification with females, a disastrous psychological and behavorial train-wreck in my teenage years, and the strong feeling I was transsexual starting in my teen years.
Non-standard elements: While I was female identified when VERY young (3 or so, perhaps ... hard to say, though I remember this), it was essentially buried shortly thereafter. I had a preference for girl's play up to my teen years, but wouldn't go there ... except in private, which I did when my sisters were out of the house (i.e., with their stuff). And GOD did I want to dress in my elementary school years, but rarely did. Dissonance kicked in early. I really wanted to be a nun for the longest time when I was a kid for example, and it never occurred to me that I could not. Very weird, but suppression kicked in more viciously later in life. As an episodic crossdresser, I purged literally every time I dressed. Couldn't stop it. Zoned out doing it. Beat myself up after then purged. And then put it completely and totally out of my mind. Over the years I became progressively more depressed and angry, isolated, and destructive. I had a meltdown a few years ago when the real issue finally came out and that was that.
Short version - I'm hypersensitive. In childhood that triggered the early *desire* to conform, then a hyper-reaction in adolescence. Full-on suppression through my adulthood created progressively greater tension until I broke.
That doesn't exactly fit the "knew since birth" narrative. I did - and didn't. I knew sometimes. Sometimes definitely, sometimes I suspected. Occasionally I even remembered. Rather than the standard narrative's conformity hiding reality bubbling right below the surface, mine is closer to reality being imprisoned in the very center of my being where it lay nascent. I compartmentalized my life, and in the process had no real life as myself. This is also why I typically describe myself as having a female identity rather than a woman's. I feel again in a very particular respect, and quite strongly, exactly how I felt in childhood. And I'm dismayed at the loss and damage in between.
[edit] I cross-posted with the reply above. On lack of identity - yes! With my real identity so thorougly buried that it only came out episodically, the rest of the time I was ADAMANT that I am NOT a man.
