what if human beings had always reproduced ASEXUALLY rather than sexually?

There would be absolutely no genetic variation would result in genetically identical species that probably are neither Male or Female. But that would also eliminate competition in terms of who is ugly, pretty, that aspect of society would be gone since everybody is exactly the same unless there are major mutations which is rare

That wouldn't be any fun...

Actually, "they" (meaning certain scientists) think it actually could be possible that in the future, humans could reproduce asexually.

Could be there wouldn't be the overwhelming emphasis on being "sexy".

It would be a world of clones. Asexual reproduction produces an exact copy.

Everyone would either be a hermaphrodite or a woman

There probably wouldn't be any porn... nooooo!

Let's see... no marriage, probably a lot less love poems/movies/stories.

And no women, that would really suck.
