For example, where exactly is this liberal sacredness around sexual autonomy?

Providing that which was specifically requested, concrete examples of liberals sacrificing human lives to sacredness in the particular matter of sexuality, will of course result in this post being marked down, and were I to point to examples of the more obvious and extreme examples of sacrificing lives for sacredness, such as the environment, it would be marked down even more.

But here goes:

Let us suppose a capitalist was doing something that frequently caused harm to others and himself, for example operating a car battery recycling center where he dumped acid containing lead sulphates in on the ground, in drains, in a nearby stream, etc. Then he would be strongly regulated and supervised.

But female sexuality frequently results in harm to their children, their husbands, and themselves, and it is pretty much unthinkable to restrict it, even in the case of a married woman with children. Similarly, the response to the AIDs epidemic was to invent an imaginary heterosexual aids epidemic, rather than shut down the bathhouses. I am pretty sure that if Chuck E Cheese's cheese was killing vast numbers of people due the frequent presence of dangerous molds in the cheese, it would be shut down very rapidly without anyone worrying about restricting the liberty of cheese eaters to eat as much cheese as they liked, in any form they liked, any place they liked.

Similarly, vaccination against certain sexually transmitted diseases. They want to vaccinate vast numbers of people that are unlikely to need it at considerable expense, and possible risk of harm, in order that those that do need don't suffer possible stigma by having to request it. If you actually wanted to provide herd immunity, you would vaccinate the main disease reservoir, which is adult male homosexuals, not schoolgirls. If this was, say, an expensive rabies vaccine, people would get it on the basis of potential exposure, and animals would get it on the basis of being a potential disease reservoir. Instead it is being targeted at those least likely to benefit, and least likely to cause risk for others, because targeting it where it might actually be most useful might stigmatize the recipients. No one seems to worry that Chuck E Cheese might be stigmatized by visits from the health inspector, and they would worry even less if some customers were dying because their cheeses had the wrong molds growing in them. On the contrary, they would think it a damned good thing if they got stigmatized for harms that they indirectly or carelessly caused.

We face a vast pile of very restrictive regulation to prevent harm to that which liberals consider sacred, on the basis of vague, small, questionable, and nebulous externalities, yet if women fail to express their sexuality in what used to be the approved channels, or express their sexuality in what used to be unapproved channels, this is apt to cause massive externalities, particularly to children. And if female sexual autonomy is sacred, unlike Chuck E Cheese's cheese, male homosexual autonomy is ten times as sacred, as we saw in the AIDS epidemic.

Cheese gets aggressively regulated for a vague, slight, and quite possibly nonexistent risk of harm. Sexual misconduct does not, despite major and alarming harm, and not only is it not regulated, but aggressively protected from social disapproval.

If someone wants to sell homemade sauerkraut at a farmer's market, they need to first hire a team of lawyers and consultants to shepherd them through the bureaucracy, lest they somehow cause inadvertent harm to their customers, but if a woman feels that sex with her husband is insufficiently fulfilling and starts banging a pimp from time to time, because the pimp is so much edgier and cooler than her husband, the entire apparatus of state is not only not going to do anything to restrain her, it is going to use violence against her husband and children to prevent them from reacting negatively to this development.
