Yes, you could argue that. But when a cuckold couple makes their decision, for reasons others can not understand, may it be basic instinct, BDSM, philosophy or just fun, they are old enough. But a baby is innocent until a certain age and cannot make their own decisions.
SO, does anyone know how terrible it is for someone not to even know who their biological ******* is? It is very destructive. If you knock up a hot wife, that's one thing, but the baby should at least know that you are the biological *******. Its also important to know, for heath safety reasons. Hereditary diseases etc,.
