Her parents want her to get married; she is 17 years old and feels that she is still too young

If the person who is proposing marriage
to you is a righteous man with a good attitude, I think that you should
agree to get married. Marriage is a natural need in both men and women,
and this is a good age to get married. May Allaah help you and bless
you with a righteous husband, and with righteous offspring.

Shaykh Muhammad al-Duwaysh.

 Girls have gotten married at a younger
age than this, and their marriages have been successful. Life is experience,
and as time goes by you will become more able to bear responsibilities.
Protecting yourself by getting married is better than remaining exposed
to the dangers of all kinds of desires and deviations, especially in
misguided societies such as the society in which you live. Seek reward
by forming a Muslim family and a Muslim home, and seek reward by keeping
a Muslim man chaste. May Allaah help us and you to do all that is good.
