This answer is from Kagi’s search summary: I don’t know how accurate it may or may not be.

As of 2024, the specific U.S. states that only define rape as requiring penis insertion are:

• Alabama
• Florida
• Idaho
• Kansas
• Louisiana
• Mississippi
• North Carolina
• Oklahoma
• South Carolina
• Texas

These states have not updated their legal definitions of rape to include other forms of sexual penetration or oral sex, which can lead to underreporting and inadequate prosecution of sexual assault cases. It is important to note that federal law and many other states have broader definitions of rape that encompass various forms of non-consensual sexual contact.
