Not true, read more. There is a close in age exemption in many jurisdictions, sometimes if the difference is less than 5 years in age and sometimes if it is 10, it's OK. Meaning if one partner is below age of consent, and the other is above it, but age diff is less than X years defined by law, it is OK in this case. For example, couples in high school where one partner is older and becomes 18 a year or two before the other does.
