Lloyd was a previously normal young man of 21 years of age, living in a nice apartment in a large American city. He lived alone but his girlfriend Ashley often visits as she only lives a few blocks away.
He will soon wake up in a world not his own, do to visiting a nearby quantum reactor. He'll swap bodies with another version of himself from an alternate universe, with basically no way back.
The universe he'll end up in is 4632, a universe much like our own but with a serious difference. While the same people and places exist, instead of two biological sexes their are four. A long with men and women their are nulls and herms.
Herms are people with the characteristics of both sexes. They have features that are a mix of both sexes and they possess both a penis and vagina.
Nulls are people with the characteristics of neither sex. They have completely neutral features like they never went through puberty and they possess no genitals whatsoever except for a small hole for urine.
All four sexes are equally as commen. And straight people are attracted to all sexes but their own.
Now, how will Lloyd awake...
