Attention … top !

I AM …

A very useful thing that in general measures 15 centimeters.

In normal times, I’m there, inert, waiting for action …

On one of my extremities is a bush of hair that I wear with arrogance.

When I am active, I am promptly and often introduced vigorously.

But some like to use me slowly.

Eeverything depends on the temperament and fitness.

However the method of employment is still the same:

Move back and forth repeatedly in a hot and humid cavity that creates a very strong excitation of the area concerned.

When my office is done,

I usually leave in the cavity a wet a white substance.

Foaming, sticky and slightly sweet.

I also have that secretion on myself and in my hair.

It is necessary to clean me for another job.

Once back to my resting state, I wisely expect my next use.

Some people could use me 2 to 3 times a day.

But few people are able to support this rate.

I am …?
I am …?
I am …?
