That's not the issue, Karu wants to know if its going to be possible to experience the game's content in its enterity (or at least a big portion of it) if we choose F/F or M/M only. Traditionally there's not much breeding involved when there's only one gender, hence why we're discussing alternative ways.
You and I have different thought processes - you prefer take things with a creative stride, I prefer to remain grounded in my ideas. You think of impossibilities, I think of ways to analyze and explain them. No need to snub here, all the crazy ideas you may have started somewhere - by seeing, mimicking and learning the world around you. Or are you telling you contacted some extraterrestrials or eldritch horrors in order to acquire "vast sums of knowledge" on how gay men may reproduce on their own?
Besides, you're the one who asked whether or not homosexuals would be able to enjoy the game's content, based on the fact breeding usually requires two genders. I'm just throwing out ideas on can gay sex produce offspring and hoping the author will consider some of it. I do this because I want to help YOU enjoy the game, or at least have a reason to play it, rather than just saying "Fudge you, go get your fun elsewhere" or "Here's a game where you can only enjoy 1/3 of due to your limited tastes, have fun". I'm trying to meet you halfway and you're honestly just being kind of a douche.
You may not care about the tecnhicalities and world-building but have you considered that maybe other people do? Its an important process in videogame development to think about the hows and whys of things, specially if you want to more than just sex in it. I also don't play these games for the fapping, I play because I like the characters, the story, the interaction, the lore and a bunch of other stuff people would consider "useless". If you don't care about that then that's your perogative but I do, hence why I "overthink" things... even if the game includes very little of it, I still hold the right to do so. No need to kick me in the ass for it. >.>
