That’s what I was saying. As someone working in medical field, anyone who has erectile dysfunction, they are diagnosed as impotency Sora
I get what you mean but that's not the type of impotence being used in the story, that wasn't an ED type of situation it was a weak sperm, like how a egg could not take sperm it's like that but reversed that's why it's called impotent
