Here's the law:
The age of consent in Wisconsin is 18 and there is no close in age exception. There is, however, a marital exception which allows a person to have sex with a minor 16 or older if they are married to the minor. If the minor is below 16 both sexual intercourse and any sexual contact are a felony; sexual intercourse with a minor 16-17 by a perpetrator who is not married to the minor is a class a misdemeanor. However, Wisconsin has a child enticement law that prohibits people of any age from taking people under 18 to a private area such as a room and exposing a sex organ to them or having the minor expose their sex organ to them. This is a class B or C felony. 948.09 Sexual intercourse with a child age 16 or older. Whoever has sexual intercourse with a child who is not the defendant’s spouse and who has attained the age of 16 years is guilty of a Class A misdemeanor.
948.02 Sexual assault of a child. (...) (2) Second degree sexual assault. Whoever has sexual contact or sexual intercourse with a person who has not attained the age of 16 years is guilty of a Class C felony.
If the minor is below 16 marriage to the minor by the accused is not a defense.
