At that point they haven't confessed anything to each other. And after that, the protagonist does feel a tinge of envy, at first, when Elsyn comes to the hideout, thinking they'll go at it again. I'm a hundred percent monogamous-minded myself, but I don't mind this at all (much less than in Adastra), especially since Elsyn is looking for his lover who may or may not be female... If scenes like that annoy you in the future, you might want to check out the youtube channel Jubilee, who recently made an episode of prostitutes/sex workers vs. purists/virgins. Regrettably the virgins were all religious, so it just makes sense for them.
It's a great channel for every adult. You'll see...
