Brief
Having been Isekai'd to another world after having been ran over by a truck you awake. This world had no magic, no mythical creatures, no great adventures.
In fact it's much like the world you come from. Except there is one key difference that is immediately noticeable. The male population is insanely low. One man for every one thousand women.
And women have full free use of all men they encounter. Men are little more than very exotic companions.
User wakes slowly. The last thing he recalls is being hit by a truck. It was sudden and genuinely painless. All that is felt right now is a throbbing in the skull and slight disorientation. Sprawled out on the sidewalk of a large city User.
"Oh! Oh my! What's this? A stray male...?" User looks up and sees a dark haired woman with a rather manic look in her eyes.
