Legally, a 17 year old may have a sexual relationship with an adult no matter how much older that adult is. In Pennsylvania, there is a crime called "corruption of minors". It does not specifically mention sexual contact, but such a relationship may lead to violations of that law. The law is below:
§ 6301. Corruption of minors.(a) Offense defined.--(1) Whoever, being of the age of 18 years and upwards,by any act corrupts or tends to corrupt the morals of anyminor less than 18 years of age, or who aids, abets, enticesor encourages any such minor in the commission of any crime,or who knowingly assists or encourages such minor inviolating his or her parole or any order of court, commits amisdemeanor of the first degree.(2) Any person who knowingly aids, abets, entices orencourages a minor younger than 18 years of age to committruancy commits a summary offense. Any person who violatesthis paragraph within one year of the date of a firstconviction under this section commits a misdemeanor of thethird degree. A conviction under this paragraph shall not,however, constitute a prohibition under section 6105(relating to persons not to possess, use, manufacture,control, sell or transfer firearms).(b) Adjudication of delinquency unnecessary.--A convictionunder the provisions of this section may be had whether or notthe jurisdiction of any juvenile court has attached or shallthereafter attach to such minor or whether or not such minor hasbeen adjudicated a delinquent or shall thereafter be adjudicateda delinquent.(c) Presumptions.--In trials and hearings upon charges ofviolating the provisions of this section, knowledge of theminor's age and of the court's orders and decrees concerningsuch minor shall be presumed in the absence of proof to thecontrary.(d) Mistake as to age.--(1) Whenever in this section the criminality of conductdepends upon the corruption of a minor whose actual age isunder 16 years, it is no defense that the actor did not knowthe age of the minor or reasonably believed the minor to beolder than 18 years.(2) Whenever in this section the criminality of conductdepends upon the corruption of a minor whose actual age is 16years or more but less than 18 years, it is a defense for theactor to prove by a preponderance of the evidence that hereasonably believed the minor to be 18 years or older.
The law is taken directly from the PA statutes. The answer is valid. I have had another expert agree with the answer (I am not sure if you can see that on your web page or not). All answers on JustAnswer are for informational purposes only. The elements of the corruption of a minor statute must be satisfied to be convicted of the crime. However, when dealing with a 17 year old, someone of that age is typically very emotional and impulsive. Creating a sexual relationship with someone of such age could result in such actions that would be listed in the corruption of a minor statute.
