A young actress named Mary Cathleen Collins, later to be known as Bo Derek, began having a sexual relationship with actor/director John Derek when she was sixteen. He was thirty years her senior. The couple lived in Germany for two years because of the possibility of statutory rape prosecution under U.S. law. They married when Bo turned 18 and stayed married until John's death.
Young people mature at vastly different rates and situations like these should be judged on a case-by-case basis.
Oh, good, when I said no one was defending statutory rape I was worried that creepy old men having sex with teenagers thanks to different laws and crazy parents might go underrepresented, so thanks for that, Doug Hutchison
