This is for Whistler, the applicable criminal code provisions from the two largest US states regarding unwelcomed touching. New York makes no distinction as to age, but California has a special law pertaining to all persons under 18.
New York:
S 240.26 Harassment in the second degree.
A person is guilty of harassment in the second degree when, with
intent to harass, annoy or alarm another person:
1. He or she strikes, shoves, kicks or otherwise subjects such other
person to physical contact, or attempts or threatens to do the same; or
2. He or she follows a person in or about a public place or places; or
3. He or she engages in a course of conduct or repeatedly commits acts
which alarm or seriously annoy such other person and which serve no
legitimate purpose.
....
Harassment in the second degree is a violation.
California:
647.6. (a) Every person who annoys or molests any child under the
age of 18 shall be punished by a fine not exceeding one thousand
dollars ($1,000), by imprisonment in a county jail not exceeding one
year, or by both the fine and imprisonment.
....
(d) (1) In any case in which a person is convicted of violating
this section and probation is granted, the court shall require
counseling as a condition of probation, unless the court makes a
written statement in the court record, that counseling would be
inappropriate or ineffective.
(2) In any case in which a person is convicted of violating this
section, and as a condition of probation, the court prohibits the
defendant from having contact with the victim, the court order
prohibiting contact shall not be modified except upon the request of
the victim and a finding by the court that the modification is in the
best interest of the victim. As used in this paragraph, "contact
with the victim" includes all physical contact, being in the presence
of the victim, communication by any means, any communication by a
third party acting on behalf of the defendant, and any gifts.
(The term "molest" in the California statute has the dictionary definition, meaning "to bother." Sexual assaults are covered in a different part of the penal code.)
