OK, this the MtF side but it easily would apply to FtM - maybe more so?
There are things we go through when we grow up, go through puberty, and for females born female (and NOT for MtFs) such things would be our first period, how to get on with it, later on loosing our virginity - becoming a woman, have our special day (white wedding?), for most to get pregnant, giving birth...
NONE of these things are part of an MtF's life... maybe some lucky ladies have a wedding, brides maids, a groom, their special day. Married life, a husband.
For all these things, there be certain parallels in a male life, they will just not have happened to us.
In other words: What if ANY, are OUR rites of passage? Transition, HRT, SRS, FFS, BA?!? to give US our 'grounding' as grown-up women?
Trans-women, OH YES! Ordinary women? Not that I can see it - not for one moment.
The lack of these experiences (rites of passage), the "normal" ones for most female born female are what gives women a certain "grounding". A grounding in WHO they are. They are THIS... and nothing other, female. Period. Just normal women.
It is my contention that the lack of our female rites of passage is one of the main reasons for our almost insurmountable insecurities. Do I pass, will I pass, can I be stealth, what is my orientation post-op, HRT, etc.
By not having gone through those experiences we will always be outsiders of some kind, to the female side of our tribe.
Can we do anything about it? I don't think so. But you tell.
BTW, it is an accepted thing in Large Group Awareness Trainings (LGAT) that the lack of such "rites of passage" leaves modern males also pretty much "afloat" – emotionally. Leaving them with an equally lesser sense of maleness, leading to some of those silly overcompensations we so often see (well, I do).
If we are going through the wrong "rite" for our gender (brain sex) it is also of little help. I did some of just that... and see what happened. I transitioned, my inner self did not benefit in the end.
Yet... now we are emotionally in some kind of female Nowhere-Land. Maybe like a female teenager in early puberty?
It comes visiting in the wee hours, when we have no one to reflect back to us "yes we are a woman" and we feel ever so ordinary just ourself in some sort of gender vacuum. Our body does not seem to count for much in these moments...
I just bring this up in a spirit of sharing and, I'd be little surprised to be the only women sans 'rites of passage' that feels that way.
Thank you for your attention
