If you are looking for mental or emotional aspects, you'll probably get better answers in the psychology section! :)

Answer 4

like someone said before,  same species but they need each other to reproduce. they act different because girls are built to give birth and be motherly, guys are meant to do all of the hard work. I'm not saying that girls can't do anything guys do, but I'm saying girls sometimes have a harder time because their bodies know they are supposed to be nursing or carrying a baby. You just have to work through it.

Answer 5

Both mammals, but not the same.

Answer 6

both belong to the same species, but need eachother to re-produce.
