what is the half your age plus 7 rule
Age disparity in sexual relationships The "never date anyone under half your age plus seven" rule is a rule of thumb sometimes used to prejudge whether an age difference is socially acceptable.[62][63][64] Although the origin of the rule is unclear, it is sometimes considered to have French origin.[62]
Ages of consent in the United States State law specifies (by not saying anything) that minors between 13 and 15 years old may, in general, engage in a consensual sexual relationship with someone up to four years older. Therefore, for example, it is legal for a 14-year-old male or female to engage in consensual sex with a person up to 18 years of age.
