Definition of Aggravated Sexual Battery
Aggravated sexual battery happens when a person “intentionally penetrates with a foreign object the sexual organ or anus of another person without their consent.”
The Code defines “foreign object” as “any article or instrument other than the sexual organ of a person.”
Again, there isn't an age or gender requirement. Consent can be a defense.
