time-travel-self incest story where main character ONLY one can’t Time Travel & I think Self Published sci-fi/fantasy?

[Topher]

What happening/going on in the book: Is a world where everyone can time travel anywhere or anytime what was commonplace was to have time-travel-self incest orgies with their future selves / Alternate selves(you as a girl if you time traveled as male vice versa) the roommate of the main character is doing this all the time. There is one part where the main character walks in on his date/girlfriend doing it as well.
The main part of the story is the fact with this all going on the main character himself is the ONLY who can’t time travel
Came out (2000-2021) About.
I think found book on Amazon as a self-published author(not sure)?
pretty sure more mainstream fiction then the erotic all section even though alot of that goes on.

I KNOW FOR A FACT THAT IS NOT THE BOOK
"THE MAN WHO FOLDED HIMSELF"

Any help you can, Thank You!

The Man Who Folded Himself probably isn't your book, since the main character is the only one who can time travel, but it does include the orgies/sex with yourself/alternate versions of yourself, so I thought I'd throw it out there in case you were somehow combining two books in your memory.

Or have you looked through any of these lists of time travel books?

Yea not “The Man who folded himself” & I have looked quite a lot through the lists of Time Travel categories on here.
When I look with both terms in searching it comes up with Adult erotic stories of the subjects & not a sci-fi/ fantasy story with a more mainstream story story
Amazon used to do more detail terms search to narrow down & now shows any book term search of the “Top 100” not previous years with the search terms of.
