Looking for old [mmm] gay erotic sci-fi story

I hope this is a good place to post this.

Around 1994, I remember finding a gay erotic sci-fi story that I enjoyed. It was about a guy who visits another planet that is populated by gay men. I’m curious if anyone might know where to find this story?

Some scenes I remember:

* He asks another guy there how they reproduce, and the other guy says they use cloning
* A scene where he and another guy are laying down on the ground making out while some anteater-like creatures give them oral until they orgasm
* A scene where he lays down on a tree stump, which has the ability to stimulate his cock until he orgasms
