When a 14 yo boy has sex with his female teacher, there is very much a sense of “lucky bastard” rather than “poor victim”, especially among males, so even when there is a trial, the woman often walks free because the judge or the jury cannot decide that something fundamentally wrong happened, especially if the boy is cocky about it (which he often is)
