So sometimes people from one gender or the other can't get sex through casual relationships through one reason or the other, like large groups of men dieing in a war, China's gender imbalance, a shitty personality, etc. Are you saying that they don't need sex at all and should go without? Because that's a pretty puritanical viewpoint that hasn't been backed up by any sort of history. Additionally "need" can be pretty subjective. People's sex drives are some thing they are born with. We don't "need" rare earth metals to have shiny electronics so why is it ok to have people forced into mining by it being their only choice economically?
