Re your question earlier, thunderbolts - sorry - I missed it due to skipping in and out during an unspeakably annoying day at work. I couldn't really speculate on the felt experience of other species - I can at least inquire about the experience of my own species, as we share a language (however imperfect) but I don't speak any animal languages so don't really have any way of enquiring what it might be like for, say, a cat or a horse.
I'm still getting this nagging feeling that we're talking at cross purposes about this idea I floated of a 'core gender identity'. I'm definitely NOT talking about some essentialist idea of the attributes that come with a biological gender, but more about the 'tacit knowledge' that people have about themselves. The kind of 'implicit identity' I'm trying to describe is usually unspoken and largely unconscious, and comes about inductively and experientially, through inhabiting the world in a physical body.
Stuff like the shape and extent of our bodies, physical urges like hunger, thirst, tiredness or sexual arousal, subtle hormonal changes throughout the month or year, mood swings, proprioception - all the implicit knowledge we have about ourselves as embodied humans. The idea I wanted to float was that this is part of how we experience ourselves, fundamental to what we can experience (senses, sensitivities, etc), rarely reflected-on, and that at least some of that experience is gendered. This becomes more marked at puberty, with adult male or female hormones, but some part at least becomes marked at a pretty early age with the idea 'male' or 'female'.
And that the idea 'male' or 'female' becomes connected to aspects of embodied experience before we grasp any of the gender role stuff that goes along with 'male' or 'female', eg that one colour is 'for boys' and another 'for girls', and all that bollocks. I'm trying to describe that point where small children become aware that their genitals aren't the same shape as their opposite-sex parent, but don't realise yet that this will increasingly come to mean they have to behave in pre-determined ways that differ for girls and boys, in order to fit in with the expectations of those around them.
Milly - I certainly have an embodied sense of myself as female: I have breasts, I get PMT, I menstruate etc etc. Of course your experience is your own, and I don't dispute it, but I'm puzzled by your statement that you have no core gender identity. I'm thinking maybe we were at cross purposes, as you said in a subsequent post that you choose to spend time in all-woman groups partly because you have 'things physically in common with other women that are important to me'. Surely those 'things physically in common with other women' are approaching what I'm trying to describe here, as an embodied sense of yourself as female?
