Is this original riddle decent for a teenager?

[Kelson]

Hello,

I am gifting my nephew a gift card in a puzzle box that requires a 5-letter answer to unlock.  I've looked up some riddles online that fit the bill, but wanted to create something unique so he wouldn't be able to solve it instantly based on past internet searches (I did this to him a couple years ago with a 3-letter puzzle box riddle so he may be curious).

Here's what I've got:

There are many of me, yet you have only 1.

Replace 1 of my letters to groom yourself.

Replace 1 of my letters to show you are humiliated.

Remove my first 2 letters and I am a human animal.

Remove my 2^nd and 5^th letters for a sweet treat.

What am I?

I don't know how to hide an answer in this forum that can be revealed by hovering over it/clicking on it, so I'll omit it for now.  Will reply later with the answer if it's not figured out soon.

I'm very much open to editing or replacing this riddle entirely - just wanted to get other people's takes on this first.

Thank you for your advice!

Initial thoughts are that

Spoiler

the second and third clues made me think of brush and blush, but left wondering how an ush could be a human animal or a bus could be considered a candy.

I came to the same conclusion as plasmid:

Spoiler

the first part could point to "brush" or "bathe"

second makes me thing of "blush" or "flush"

stuck on where to go from here...

I think the phrase "human animal" is really throwing me off for some reason.

Not allowed to edit the above comment anymore, I'll keep adding thoughts as they come to me.

"groom yourself" - brush, bathe, style, 

"humiliated" - blush, flush, flame, cower, 

"human animal" - the, she, ape... ape might work

WORKING WITH APE: 

"sweet treat" - _ x a p x --> cap (like nightcap), sap (like syrup)...

WORKING WITH SAP:

[ s_ape ]

"groom yourself" --> shape

"humiliated" --> shame

ape

sap

The only thing I could really think of for the answer would be "shape," but that either means I have the final answer or the first part (groom) wrong. 
 

GROOM YOURSELF IS SHAVE ISNT IT!
 

Final Answer:

ANSWER: Shape

Shave

Shame

Ape

Sap

Did I get it?
