Well, the porn-focused part of me would say massive lesbian orgies and wars waged solely by lingerie catfights.

In all seriousness, this actually isn't nearly as bad a scenario as all women dying off, because if sperm banks are still in operation the human race could be repopulated near-indefinitely, even if all the resulting babies are girls, as well...and even if the sperm runs out I have heard that it could be possible for lesbian couples to produce babies which are 100% biologically theirs (basically, one egg gets fertilized by another egg which is spun into a sperm...somehow).

Now you're talking ;)

Lots of long grass in yards.lol

Lots of scissoring probably.

Read the comic Y: The Last Man...it's close enough to this premise

Sperm banks will make most business.

Less football on the TV

A rise in intelligence? :P

Glad I'm not around to witness that pms filled hell.

Women would evolve so they can create offspring together.

We'd all become lesbians and watch the human race die off.

In the overall scope of time when the sperm banks become empty we can say goodby to the human race .

What a lovely adult movie that would make! I could pick out the cast by name, and their acting is actually pretty darn good!

Folks would stop wearing make up and get fat ? And again, no more people. 😅
