*The 'problem' with this situation is that above all there needs to be communication. And for some people talking about sexual things is difficult in the first place, let alone trying to find a 'right way' to tell your partner that you'd like them to (basically) leave you alone, at least until you've caught your breath and figured it out. The OP is going to have to talk to her partner and his reaction will tell her all she needs to know.
Most men tend to feel that love = sex so they may take it as a personal rejection when we tell them "A little less, please". A caring man who thinks he is offering 'love' will try to understand, slow down, and seek compromise. Of course, some men are pigs and just want sex, period, with nothing to do with love. A pig will get butt-hurt and offended. OP's partners reaction will tell her all she needs to know.*
This is absolutely bang on.
But let's not frame it as a "men want this, women want that" thing - I think most women would feel hurt, unattractive and rejected if their husbands suddenly went off sex with no explanation. Indeed we see just as many threads about that on here. (Invariably the response is "LTB if he doesn't give you what you need", which is certainly different to the responses here.)
Women don't owe men sex at all, for anything, in any way. But two people in a relationship owe each other communication and respect. OP needs to explain to her husband why she doesn't want sex, and explain that it doesn't mean she's rejecting him or finds him unattractive or doesn't love him. And in turn he needs to listen to her, understand her and respect that.
