Rabid Chocolate Chip
I always found infantilism fascinating.
Especially since I still cling to some things from my childhood. (I don't think it necessarily fall under 'infantilism' but it made me feel better that I wasn't the only 19-year-old who still engaged in activities and things from when I was much younger.)
I personally think it would be awesome to have a 'mommy/daddy' figure....but most of my friends would look at me like I had three heads if I told them that, lol.
If you genuinely like the idea of a mommy/daddy figure but don't feel you fall into the infantilism category, Age Play may be for you.
Here's the best link and most legal link I can give you for this purpose, I would search for more but finding information on a website WITHOUT awkward pictures is difficult (And being that I don't know your age, possibly illegal to link you to more questionable material).
So. On that note, check this site out. I've PMed you a copy of this post just in case you were just dropping by.

Edit: Or I WOULD have PMed you a copy. Instead I'll just drop you a comment.
