Did you guys ever read a science fiction book about a group of travelers visitin

I remember reading a book where these people had a vehicle like a car except it could travel to other earths by just putting in the coordinates. They had a group I believe two guys and 2 or 3 females. The females wanted a relatively warm earth and they wanted to pick an earth not where everyone was nude or nude on the beach but one where they could wear some thong like bikinis to show off their body claiming they got lots more attention not being completely nude but when they wore bikinis that showed off their body without covering up anything important. At some point in my past, I read all these sexual stories and I'm trying to remember where and when and who gave me all that stuff to read. I know one high school teacher gave the class a bunch of sexual stories to read. He claimed it was part of history or something like that. In that fucked up story a high school teacher gave me to read, there was a story of how some guys had sex with some girls with teeth in their vaginas without getting eaten. They had carved some wood dildos and broke out the girls vagina teeth. Then supposedly, the girls no longer had teeth in their vaginas. So I'm just wondering, did everyone else read all those weird stories in high school or anything like that?

As far as the science fiction story, I might have read a science fiction novel on my own with a sexual side to it. I used to read books when I was younger before everyone had a computer or smart device. One series that no one converted to movies that I would like to see were the Mission to Planet Earth novels. It involved an alien involved in human affairs. It had terrorism, explosions, covering tracks, secret organizations, and leaving the planet and having a federation of planets ban our star system as off limits due to our perverse method of governments and laws. Apparently the aliens thought we were a major hazard to the rest of the universe. Not any weird freaky sex stories in those novels though.

I read it before but forgot. I heard Isaac Asimov, a famous science fiction writer is positively viewed in the Middle East because the so called Foundation in his novels translates to Al Quada or something like that. That's just weird in my opinion.
