And when it comes to morality, that's something you can only define for yourself.
Well the point of his coming here to discuss the ethics of it was to go beyond his own starting moral intuitions, to consider arguments and perspectives that pertain to the ethics of the act in question. The view that morality is a personal matter is a non-starter as far as moral philosophy goes. The ball is in OP's court over who/what to consult to find relevant ethical considerations, and it's up to him to reason those out and whether to follow them, but that doesn't make the ethics itself something for him to define.
