A ephebophile is a older adult who are sexually attracted to 15 and 19.
It really grinds my gears that society doesn’t have a problem with a 18 year old having consensual sex with a 17-year-old. Even though the 18 year old is an adult and the 17 year old is a minor. But if 26 year old has consensual sex with a 18 year old. Ah then society has a problem. But why should that be a problem? When both actions are completely harmless as long as both people are consenting adults.
Culture and law aside, I think the real fear is that there’s a power imbalance that makes it questionably consensual, if you actually have such a relationship.
