I mean, I think I understand, about the muscular woman, i mean the feeling of knowing that something that could easily kill you obeys you without question, like a feeling of power and feeling of superiority knowing that even being physically inferior you can still easily handle the situation. Sorry if I interpreted it the wrong way.
But going back to my initial point, it is precisely for this same reason that I prefer hypno, since it essentially represents the same thing but due to how common this pokemon is for this type of story, it generates a certain familiarity and routine in the method, for this reason it generates attraction to the idea of being the one in control of the situation, that's why I prefer to control a hypno than a machoke, but still, I respect your opinion
That was part of it, the part that I thought might line up with your interests, but there's the other side of control—not having it—and my interpretation of that is what tips me much more in favor of Machoke and Machamp.
Hypno being in control is likely only going to be hardcore domination, because, well, hypnosis powers. Duh. At its gentlest, it might be able to let one "switch off" their brain, but that's kind of a difficult fantasy to write and verges on just being magical alcohol.
Machamp being in control, on the other hand, could focus on the feelings physical intimacy, security, and comfort, as the big, strong woman who will give one a bit of respite from the world. That's what I was getting at with the Alolan riding Machamp: it's not something I'd want a lot, but I think having a strong woman carrying me, cradled in her bosom, would be a soothing experience. Or to spell out plainly, Machamp is physically strong enough that it could mother an adult, and sometimes being able to let go is really nice.
