Reversed Libidos Multiverse

This is an anthology set in a variety of universes where the women are hornier than the men, with variations on that main theme. The women could be ravenously sex-obsessed, barely able to control themselves, or they could simply be more motivated to initiate than their male counterparts. Depends on the characters and the specific setting.

The one constant is that this isn't a multiverse where women have become Amazonians. If you like reading that sort of thing, there are plenty of other stories on this website that scratch that itch. Here, the men are physically far stronger and usually larger.

However, there are other changes to keep humanity balanced/plausible. In particular, in most of these settings, either the men will be the ones getting pregnant or each woman will naturally be able to turn off her ability to be impregnated. Or maybe she lays eggs that the man then has to take care of. Point is, a society where women have historically had to deal with the lioness's share of the consequences of sex wouldn't also develop women who are overwhelmingly promiscuous. That's just a simple fact that anyone serious about world-building has to deal with.

Okay, let's look at our story branches!
