It doesn't sound as if you recognize the concept of an obligation at all. Yes, we all have agency. Locking someone in a room without their consent is illegal. Taking someone's money without their consent is illegal as well. But I am nevertheless obliged to remain at work until 5:30, and my boss is obliged to pay me. When we enter into relationships of any type with other people, we willingly sacrifice our agency in myriad ways. Sometimes you have to meet people halfway on things. And sex isn't some super special thing that sits untouchably above all the rest of social interaction - it's just one more thing that, invariably and in many ways, you will have to compromise on.

Yeah, the parent seems to think that expecting sex after entering a monogamous relationship is almost rape. People are so concerned with infringing on other people's "rights" and obtaining conscent for everything under the sun, that they just can't understand the idea of obligations or responsibilities anymore.
Marriage is a huge responsibility. Entering into it means you agree to the responsibilities it carries. Each person should be well aware of these responsibilities before entering into one.
If your partner is in the mood for sex but you aren't on a regular basis, maybe a little bit of self sacrifice is needed. I'm sure the other person has helped them out doing their chores when they weren't feeling like it, or going out of their way for them in some way. Marriage is all about each person trying to give more to it than the other. I don't know why sex I suddenly a taboo topic when it comes to rights and responsibilities.
I've seen plenty of cleaning-averse husbands hire a maid to solve chore-related relationship problems. Hell, the maid does a better job, so everyone is happier. This is not really an option for a mismatched libido, so the situation is trickier. Especially as libidos can change differently with age, a couple can't entirely know what they are getting into.
Put another way, both withholding sex and insisting on monogamy simultaneously is a shitty thing to do IMO, so I sort of agree with you. But it is also tough for me to judge someone too much for doing so in a culture where anything but strict monogamy is taboo.
For a concrete example, let's say a woman feels nauseous from the smell of cooking while she is pregnant. I do not think it is the duty of that woman to soldier through it and continue to cook. But in this situation the partner can obtain food from anywhere else that is willing to serve. If the partner instead was only able to eat food that one of them had cooked, it would be tougher on the relationship for the woman to not cook at all for 9 months straight.
So yeah compromise and sacrifice are part of a relationship, and I don't think sex should be excluded from that. But at the same time it is unrealistic to reach a good solution with mismatched libidos, because even a perfect compromise can leave both parties dissatisfied/uncomfortable. Is the solution to just end the relationship? If it is otherwise a good one I don't think so, but strict monogamy makes this a harder call.
More generally I think people are looking for too much in a single package. To find someone that would be compatible with you over nearly your entire lifetime as a housemate, a co-parent, a friend, a financial partner, etc. all rolled into one is hard enough. When you start prioritizing sexual compatibility in this choice, good luck not having to compromise on other features. But if sex wasn't seen as exclusive it wouldn't need to be considered to the same extent in choosing a life partner.
You're basically arguing against monogamy though. My comment assumes a monogamous relationship, and that both people went into it knowing it was monogamous and being okay with that. Seeking sex elsewhere in a monogamous relationship... Isn't monogamous.

Going on about consent isn't either.
