性行為
As an example, Section 3101 of the Pennsylvania Consolidated Statutes defines 'deviate sexual intercourse' as 'Sexual intercourse per os or per anus between human beings and any form of sexual intercourse with an animal. The term also includes penetration, however slight, of the genitals or anus of another person with a foreign object for any purpose other than good faith medical, hygienic or law enforcement procedures.' On March 31, 1995, 'Section 3124. Voluntary deviate sexual intercourse' was repealed; it was no longer considered a criminal offense to engage in such activity voluntarily.
