It really depends on the target audience and the genre of the young adult novel. Generally, it's best to keep it relatively subtle and avoid overly graphic descriptions.
In most cases, sex in a young adult novel should be hinted at rather than explicitly detailed. This is to maintain an appropriate level of maturity and to not overwhelm the young readers. Focus should be more on emotional connections and character development related to romantic relationships.
The explicitness of sex in a young adult novel is quite limited. Publishers and authors often strive to strike a balance that respects the age group's innocence and development. Any mentions of sex should be handled delicately and within the bounds of good taste and educational value.
