It's wrong to think that your knowledge plateaus. Even after many years there are things you're still picking up and learning especially in the trans-sphere. I've been trying out a different bra to improve my cleavage and a more realistic shape. Trying out more sleeveless tops after getting over paranoia over my shoulders being seen as too masculine. And practising a winged eye-liner style. So off I go to Swindon Pride having tried all three. A raincoat covering one and two, as for three, it's still a work in progress.
