Uh, well, I've been into this for about 5 years. A good friend I met online wanted a roleplay involving it because furries, and at first I was uncomfortable cuz, yknow, social stigma, but then he explained the regression part and I immediately fell in love with it. I'm classified as adult baby, then, and I'm no lifestyler but it's a nice stress relief tool.
As far as how being a furry plays into it, they aren't mutually exclusive but I don't need onw to have the other. I do er, whimper when I'm regressed so i guess its kinda intrinsically linked.
I came to this site because I've never been able to openly discuss this with anyone and its felt kinda lonely so I'm hoping I won't have be quite as alone in this thing. And also because saying the teeminology out loud is difficult cuz I'm not... er.. comfortable with that aspect of myself yet
