Thank you for all the replies. There doesn't seem to be a multi-quote feature for replying to numerous posts (or if there is, I can't find it).
But I will say that I wasn't trying to judge other people here, or disapprove of their hobbies.
My fella and I go to a few model engineering shows and exhibitions each year (indeed I help to run and exhibit at some), and it's always totally male dominated. In fact in all my years of going to such shows, I have only met 5 women who are model engineers like me, and three of them were transgendered. Compare that to 1000's of guys I've met, female model engineers are such a tiny minority.
When guys speak to us at the shows, they always address my fella as they assume I'm not interested in the subject and know nothing about it. I don't mind this, as it reinforces to me that I pass. My fella finds it hilarious as he knows it's me who's more into the subject than him. I sometimes get him to ask questions on my behalf or push to the front to get items I want, as I'm usually ignored.
But it does take a lot of my confidence to partake, as when folks find out I'm not just a bored wife being dragged around by hubby, inevitably I'm suddenly in the limelight and being asked lots of questions because I'm such a rarity in these circles. I've lost track of the number of times guys have asked me to marry them/proposed, as they like the idea of sharing their life interests with a female partner.
I am certainly not trying to impress anyone, but I won't deny, I get on with guys better than women, and generally like being around men.
None of the above reinforces my femininity though.
I lack female friends, and I suppose I do need validation of my legitimacy as a female among women.
I do have female friends, and I'm fine spending time with them, but I never feel I really "click" as 'one of the girls'. Especially when they talk to me about experiences that I've never had, like 'time of the month problems' and childbirth and being a mum. I try to blag it through as best I can, but still end up feeling an outsider. It doesn't help that people usually see me with my fella and his young son, and just assume it's my child. It's nice, that people see me like that of course, but I do feel pangs of guilt and angst that it's not 100% reality.
Anyway, I've strayed massively off topic, and I apologise for that.
In order to raise my spirits and because I love my hobby, I've been tool shopping again, and have treated myself to some nice kit for the workshop.
I guess after so many years of being in 100% 'stealth', I find I just really need to talk about the things that affect me as a transexual woman.
