I’ll assume the trouble you’re referring to are the examples you listed.
Rape culture is a second-wave feminist theory that blames society rather than the individual. Rape culture was defined sometime in the 1960s, almost a decade before abortion became mainstream. Rape culture is not a criticism of recreational sex, but rather a criticism of the societal habit of victim shaming which stems from viewing women as mere property.
Rape has been far more prevalent in society than recreational sex since the dawn of civilization. And neither are mere 20th century constructs.
People don’t stay in toxic relations due to recreational sex. They stay in toxic relationships in the absence of independent financial stability or the absence of the option of divorce. Which, in a strictly theocratic society would make this more common, not less.
Abortion has been used in various ways in historical culture. Pregnancies have been terminated for political reasons to prevent a child of two warring factions, even religious reasons because someone impregnated a woman above or below their caste, racist reasons to prevent the mixing of two races, medical reasons to save the life of the mother in a botched pregnancy, population control, etc. Recreational sex is not the sole reason abortion exists.
Lastly, I understand wanting to eliminate elective abortions but not at the cost of procedures or alternatives that are medically necessary. If your stance against abortion and recreational sex is solely to prevent the higher cost of life, but are willing to sacrifice the hundreds of women who will die each year without such options as a comprise to just make elective abortions illegal, then you don’t care about individuals or choices but control. Control of people, control over the numbers. You reveal that making abortion illegal or your vendetta against recreational sex was never about saving lives.
Nor making their lives better.
