A woman's face with Nature's own hand painted,
Hast thou the Master Mistress of my passion,
A woman's gentle heart but not acquainted
With shifting change as is false women's fashion,
An eye more bright than theirs, less false in rolling,
Gilding the object whereupon it gazeth,
A man in hue all hues in his controlling,
Which steals men's eyes and women's souls amazeth.
And for a woman wert thou first created,
Till Nature as she wrought thee fell a-doting,
And by addition me of thee defeated,
By adding one thing to my purpose nothing.
But since she prick'd thee out for women's pleasure
Mine be thy love and thy love's use their treasure.
(William Shakespeare)

I suppose Shakespeare didn't purposely chose a title for this sonnet in order to let the reader guess the meaning of it.
This little poem is made up of three quatrains and a couplet.
The first quatrain introduces the physical details and the behaviour of the character, while the second one analyses the personal elements that are mentioned in the first quatrain like "eye".
The last quatrain deals with the concept of Nature which is a repetition of the first line.
The couplet is the poet's reflection on the meaning of his sonnet.
The sonnet has an alternate rhyme scheme (painted, acquainted; passion, fashion; rolling, controlling; gazeth, amazeth; created, defeated; doting, nothing) and, as i said before, a couplet with two rhyming lines (pleasure, treasure).
Shakespeare wants to describe human beauty created by Nature but the most important physical element of this man who has the beauty of woman are the eyes and the face because trough them Nature expresses the positive aspects of people.

In my opinion the sonnet could be devided into two parts because they represent two different aspects.

In the first eight lines Shakespeare introduces the ambiguous beuaty of this young man created by Nature. I use the word "ambiguous" as Nature is female and she needs to fall in love with a male who is nothing but a woman.

The second part is more personal. As a matter of fact the poet, even if he is dobious, accepts what Nature has created.

What surprises me is the natural way in which Shakespeare handless the problem of homosexuality, so we can say that he is the one who anticipates an issue of our days.

Finally, I'm sure that the sonnet teaches us to consider not only the love between a man and a woman but also a love that people usually tend to see as unnatural, wrong and shameful.
