Where in the poem, Sir Gawain and the Green Knight, does Gawain show chastity?I am doing a project and need to show how Gawain exhibits chastity,...

In Sir Gawain and the Green Knight,
Gawain holds to his vows of chastity when Lady Bertilak tries to seduce
him.

In Book III, section 49, Lady Bertilak makes her first
move on Gawain.

I have closed the door,
it's securely locked;
and since I have in this house he
whom all admire,
I shall spend my time in speech I am
sure
to treasure.
My person's
yours, of course,
to see you take your
pleasure;
I am obliged,
perforce,
to serve you at your
leisure." 

She
has locked the door, and tells him she is there for his pleasure. However, in section
51, he resists her
seduction:

...I am
proud to be prized so highly.
I am your sober servant and
you my sovereign queen --
I have become your knight and may
Christ reward you."
Thus till mid-morning passed they made
conversation;
and always she acted as if she adored
him;
while Gawain was guarded though gracious
enough.

Gawain diplomatically says no
but tells her he is hers to command, asking that Christ reward her. However, she wants a
kiss, saying perhaps he is not the gracious Gawain after all, as he
has not asked for one. In section
52:

How could the complete paragon of
perfect behavior
spend so much time speaking with a
lady
without craving a kiss in courteous
fashion
by a tactful hint or turn of
conversation?"
"Very well," said Gawain, "your wishes will
guide me,
I shall kiss when called upon, as becomes a
knight
who would not upset you.

So they kiss, he saying that he
doesn't want to offend her (a gallant, chivalrous knight would not do
so).

[The answers above come from a site that provides information
from the following locations within the text - Book III
(Lines 1126-1319, sections
46-52).]

Another version (rpolibrary...) of section 52
from above reads:

Then said Gawain, 'Let it be as
thou dost wish. I will kiss if thou dost command, as befits a knight who fears to
displease thee, so let there be an end to thy pleading.' With that she came near to him
and caught him in her arms and bent down gracefully and kissed the knight, and they
commended each other to Christ.

In
section/stanza 59 (same, new site), Lady Bertilak tells Gawain on the second morning,
that he could force her kiss him, but he says that would not be
gallant: she need only ask. But still, this is all he
does:

By my faith,' quoth that fair
one, 'thou shalt not be denied, for thou art strong enough to constrain one if thou
likest, if any were so vilIanous as to refuse thee.' 'Yea, surely,' quoth Gawain, 'good
is thy speech, but to threaten a lady is deemed ungallant in the land where I live, as
also are all gifts given without good will. I am at your service to kiss when thou
likest. Thou mayest take it or leave it when it pleaseth
thee,

in
space
The lady bendeth low,
And comely kisses his face,

Much love-talk doth flow
Of love's joy and
grace.]

The lady approaches him a third time,
pushing him to make love to her.
(71)

He cared much for his courtesy, lest he
should prove himself craven-hearted, and yet much more for the mischief that would
follow were he to commit sin and betray the lord who was his host in that castle. 'God
shield us,' said he, 'this shall not befall us,' and with spare love, laughing, he
received all the words of choice that fell from her
lips.

He does not want to be discourteous, but
refuses. She wonders if he has a mistress; he says no. She asks for a kiss:
 (72)

Kiss me now comely, and I will hie me
hence. I can only mourn in the world as lovers
do.'

This is all he will do, remaining
chaste.
