Arsenic Sweeties
I'm afraid I only skim-read your post (sorry, far too tired to concentrate on it fully), but, although I don't like infantilism, I agree with you.
There's been a couple of threads recently based around fetishes- both 'general' fetishes and specific ones, and for the umpteenth time, I'll say that, so long as nobody's exploited or hurt, you can do whatever the hell you want. I might not approve, I might think it's odd, but I can't really judge you based on what you get up to in your own free time.
Alot of people I know who are into 'weird' things are actually good people. They can accept that their fetish is out there, and in fact, most can even take the mockery that comes with it (to an extent of course. Everyone has their limits).
Agreed...you state that your psychologists say there is no mental illness in you. As long as you aren't hurting yourself, family, or friends, then it's probably just a harmless pastime, though not one that I, myself, would engage in.
Now it's time for my nap!
