"Do you know who I am?"

Do you know who I am?

I'm dark brown in color, and sometimes white,
I'm terribly desirable, and very well liked,
By those who love me, they crave me too,
If only you knew me, you'd feel that way too.

I'm enjoyed by men, and women alike,
But in me is where women, find true delight.

Have you guessed who I am?
Do you at least have a clue?
Shall I engage you further?
Yes, let me do that for you.

Now I'm not all good, I'm sometimes bad,
To the very one's who love me, I deliberately make sad.

To over indulge, might bring strife,
I can bring true havoc right into your life.

I stand alone, and accept all blame,
Do you know me now?
Have you guessed my name?

If you don't know me by now, and still can't guess,
It's time I put your mind to rest.

I Am, _ H _ C _ L _ T _ !
