It really depends on the individual. For all we know, the kid had some game and swooned a vulnerable teacher, much like some young developed girl could seduce a vulnerable adult male with a broken moral compass. That said, it could fuck a male up, just as easily as a female. It's a boy engaging in sexual acts with an adult, who might look at them as nothing but a piece of meat, where the kid is most likely in love. The bitch abandons them, and then their whole outlook on relationships and women, could permanently be distorted. And that's the mildest of effects. A boy could still feel completely violated and helpless all the same, scarring them for life and leading them down a dark path. There are boys who get abused by crazy female relatives all the time, and just because Aunt Edna has tits and gets them excited, doesn't mean the kid is all cool with it and it can't fuck them up.
