Don't forget that if a 21 year old has consensual sex with a 15 year old, he might end up ostracized on national TV (To Catch a Predator), arrested, thrown in prison, and forced to register as a sex offender for life, while in France or Italy (among many other countries) there would be no story and both parties would continue life as usual, possibly getting married and having kids (as did many couples of similar age a couple of generations ago). It is troubling that age alone determines whether a rape occurred. That is insulting to real rape victims.
