Mankind has two purposes, the survival of the individual, and survival of the species; without either we would not be having this discussion, as mankind would not exist. That’s about as finite as it gets. Survival of the species requires procreation on a massive level, to account for genetic defects, or again the species does not survive. Anything that prevents that is a defect, even by your standards.
Mankind may have only two purposes; I can't say for sure since I'm not omniscient. Still I would hesitate to try to limit males in that way. I'd prefer to believe that men could have more purposes than that, to at least give them credit for the possibility.
Humankind, however, I'm certain has more than two purposes; because neither of the ones you mentioned are mine. And, as I understand it, humankind includes women.
Many types of beings (mammals, fish, insects) have biological mechanisms that kick in under certain conditions which naturally limit their production of progeny. These mechanisms are also tied to the survival of the species because without them the species could overpopulate and become extinct through the destruction of the environment it needs to survive.
If humans don't have natural mechanisms to prevent excessive progeny, then human won't survive. So, by your logic, homosexuality can't be a defect because it serves a needed role in human survival. The role of helping to prevent overpopulation.
