If the knowledge was only dad’s preferences in women, sure, mostly harmless. The damaging part of this would be the villianification sexual desire. You’re telling someone that a normal part of having a body is wrong and you should feel shame for it. You’re also thrusting the responsibility for the parent’s impulses onto a minor.
I’m also not naive enough to believe that they had any serious, healthy discussions about sexual urges beforehand. This is the right, its just indoctrinating them onto the shame and guilt spiral as soon as possible.
I just picked up the civ5 bundle for 90% off about a month ago. It is a 13 year old game, but it’s still a great game.
