There's an elephant in the room that many Christians and churches won't address. which is that, at a certain age or point, abstinence simply becomes downright unreasonable.
It's one thing to tell teenagers or people in their 20s to abstain; people usually got married in their late teens in the Biblical era. But when believers are in their 30s, 40s, 50s or even 60s, abstinence is simply downright ridiculous and unreasonable.
Take the example of a Christian woman who doesn't get married until her 50s or even beyond (and yes, such women do exist - I know of one myself, personally.) Does this commandment literally mean that she should shouldn't have sex until getting married at, say, age 56? At that age, she has going through her entire child-fertility cycle without once having sex, thus preventing her from ever having biological children. It's an utter absurdity.
Sure, some will say, "Well, she should have gotten married sooner." But that's not always possible - sometimes, God simply does not bring the right spouse/person into one's life until one is fairly old - 40s, 50s or beyond. So one is supposed to remain sexless ALL THE TIME until then?
