Is it legal for a 19 year old to have sex with a 17 year old in PA?

There should be more to the statute...usually there is some stipulation that you can not be four years or more older than the other person...

The age of consent in Pennsylvania is 16 years of age for statutory sexual assault and 18 years for corruption of minors.

Teenagers aged 13, 14 and 15 may or may not be able to legally engage in sexual activity with partners who are less than 4 years older. Such partners could not be prosecuted under statutory rape laws, but may be liable for other offenses, even when the sexual activity is consensual.

Under Pennsylvania law, a defendant is strictly liable for the offense of rape, a felony of the first degree, when the complainant is 12 or younger. Pennsylvania has enacted several other strict liability sexual offenses when the complainant is under 16, but 13 years old or older.

§ 3122.1. Statutory sexual assault.

Except as provided in section 3121 (relating to rape), a person commits a felony of the second degree when that person engages in sexual intercourse with a complainant under the age of 16 years and that person is four or more years older than the complainant and the complainant and the person are not married to each other.

§ 3125 Aggravated indecent assault

(7) the complainant is less than 13 years of age; or (8) the complainant is less than 16 years of age and the person is four or more years older than the complainant and the complainant and the person are not married to each other. (b) Aggravated indecent assault of a child.–A person commits aggravated indecent assault of a child when the person violates subsection (a)(1), (2), (3), (4), (5) or (6) and the complainant is less than 13 years of age.

§ 3123 Involuntary deviate sexual intercourse

(7) who is less than 16 years of age and the person is four or more years older than the complainant and the complainant and person are not married to each other.

When the alleged victim is 16 or older and less than 18 years of age, and the alleged offender is over the age of 18, the Commonwealth may charge the offense of corruption of minors or unlawful contact with a minor, even if the activity was consensual:

§ 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 any minor less than 18 years of age, or who aids, abets, entices or encourages any such minor in the commission of any crime, or who knowingly assists or encourages such minor in violating his or her parole or any order of court, commits a misdemeanor of the first degree.

The crime of corruption of minors is usually a crime that accompanies another “more serious” crime such as statutory rape or involuntary deviate sexual intercourse or accompanies some drug or alcohol use, possession or sale. Tending to corrupt like contributing to delinquency is a broad term involving conduct toward a child in an unlimited variety of ways which tends to produce or to encourage or to continue conduct of the child which would amount to delinquent conduct.”

The question of whether consensual intercourse with a minor 16 years or older tends to corrupt the morals of that minor is a jury question to be decided by the “common sense of the community.”

§ 6318. Unlawful contact with minor.

(a) Offense defined.–A person commits an offense if he is intentionally in contact with a minor, or a law enforcement officer acting in the performance of his duties who has assumed the identity of a minor, for the purpose of engaging in an activity prohibited under any of the following, and either the person initiating the contact or the person being contacted is within this Commonwealth: (1) Any of the offenses enumerated in Chapter 31 (relating to sexual offenses). (2) Open lewdness as defined in section 5901 (relating to open lewdness). (3) Prostitution as defined in section 5902 (relating to prostitution and related offenses). (4) Obscene and other sexual materials and performances as defined in section 5903 (relating to obscene and other sexual materials and performances). (5) Sexual abuse of children as defined in section 6312 (relating to sexual abuse of children). (6) Sexual exploitation of children as defined in section 6320 (relating to sexual exploitation of children).
