I still can't pinpoint a beginning. The influence of dolphin was from a very young age. My parents were going through my childhood drawings recently: the earliest has the caption "dog after fox" in my mothers writing. I was 4. Perhaps I've always been this way.
I think it pretty much affects all that I do, as it is responsible for framework that defines myself and my morality. Understanding a non-furry viewpoint is that hard task. Perhaps the most significant areas are my sensual experiences: smell and touch are very important to me.
I have shifting experiences and furry dreams on an irregular basis. I make various furry vocalisations and mannerisms. I'll admit I do often meow and use other cat noises - this is the influence of those cats I live with.
I don't engage in on-line play often. I suspect much of this is due to worries about call charges - perhaps things might be different when flat rate calls are more common, but I get nervous if the Tx and Rx lights aren't on solid! Use that bandwidth!
Its fairly well controlled. It can break though in some situations, but these are fairly predictable. I've had a few incidents where I really wasn't in control, including one powerful shift in central London where I bolted across Piccadilly to the perceived safety of the park. I could easily have been run over. Recently, prescription drugs I've had to use have affected my level of self control.
Not to a huge extent: vocalisations and scritchies are about the limit.
It may be responsible for my caution with new people. Being somewhat more aurally focused than most, I tend to listen without looking, keeping my eyes scanning my surroundings. This doesn't go down well, and can make folks think I'm shifty.
More, definitely. The longer I spend in furry company the more of it shows.
Very few non-furs know. My parents know _very_ little. Ailsa, who I live with knows and tolerates it. She remains curious about the underlying spirituality.
