Alrighty, the thing about the male/remale thing is for later on. Obviously, you can't catch 99 frogs on the first go, so if you leave at least one male and female frog, aloung with the golden frog, then the swamps will regenerate faster, so you can catch more. Simple as that. It does still take a while, though, and a lot of luck not to leave just two of the same gender. Good luck, you'll need it, and a healthy dose of patience!
