In any prosecution for an offense, it is a defense that the victim consented to the act done, provided that:

1. (1) The act did not involve or threaten physical injury; and
2. (2) Such consent negatives an element of the offense.

Any person who enters the presence of other people consents to the normal physical contacts incident to such presence.
