"The only reason to wait a month for sex is if she's 17 years, 11 months old"

This quote by Barney Stinson is an amusing method of stating that it is not suitable to participate in sex with someone who is not of legal age. In the United States, the legal age of approval is 18 years old, so waiting a month for sex is necessary if the individual is 17 years and 11 months old. This quote is a pointer that it is very important to respect the laws and limits of consent. It is also a suggestion that it is necessary to be knowledgeable about the age of the individual you are engaging in sex with. It is essential to be aware of the laws and guidelines in your area and to always respect the limits of approval. This quote is a humorous method of reminding individuals to be familiar with the laws and regulations in their location and to always appreciate the borders of permission.
