Okay. So. Remember how I said about how human reproduction works by one of the genetic predecessors hosting said egg? More specifically how it works is that biologically female humans will regularly produce viable eggs that the body will then dispose of later if they aren't fertilized within a certain period. Meanwhile, biologically male humans produce reproductive material that can be use to fertilize those eggs.
This is done in the most traditional form of human sex, in which a biologically male human inserts their penis into the biologically female human's vagina and moves within it until orgasm, at which point the biologically male human's genetic material is then spilled deep within the biologically female's anatomy and travels to where her eggs are hosted during their time of potential fertility. If those eggs are able to be fertilized and the genetic material is still good, this can result in the fertilized egg growing into an infant human.
A condom is a kind of prophylactic: a thin latex sheath worn over the biologically male human's penis and used to make sure that the human reproductive material doesn't make its way to the biologically female human's egg, so it won't be fertilized if the humans in question don't wish to reproduce. Since human genetic material isn't produced in such vast quantities as troll genetic material seems to be, it's very possible to do so.
(I'm talking about biological sex rather than gender, given that there are human males with biologically female anatomies as well as the reverse, of course.)
Condoms can also be worn to avoid the spread of sexually transmitted infections during penetrative sex--or at least they were back home. I'm not entirely sure how many STIs actually exist in this world. If you have a regular partner and you have both been thoroughly tested--and you don't plan on doing any sex with them which would result in reproduction--then they can be done without. But if you're not planning to have a regular partner, then I suggest you and irregular partners wear them.
