If person x hypnotizes person y, making person y have their way with person x, with person x and y being female and male respectively, is it femsub or malesub? The male is the one being mind-controlled, but they're also the one calling the shots on the actual action. Delete this if this question's been answered, but I'm confused.

I feel like there's a grey area here and you could just say both.

you could say both, and include the hypnotized hypnotist tag as well, if person X hypnotized person Y to hypnotize person X.

That would be femdom, malesub, and hypnotized_dom, which is different from hypnotized_hypnotist.

Yup, I'd say that sounds like the accurate answer. I don't feel like, on this Hub at any rate, you'd call "malesub" and "femsub" anything that doesn't involve a guy and a girl, respectively, getting hypnotized.

Now, that's not to say that all images have been appropriately tagged. I have seen cases where what OP is describing seems to have been tagged with maledom and femdom.

Male sub and female sub are reserved for those in under the control of a tist submission . If the tist orders the sub to have sex with them that is a command so the roles have not changed.

So no, ordering someone to have sex does not make them a sub at all

I'd say those pictures get the femdom, and malesub tags definitely.

If the female hypnotist orders the male sub to have their way with her, and he does so by using bondage or the like, without using hypnosis, there would only a hypnotized_dom tag.

If the male sub does hypnotise her back, he becomes the hypnotized_hypnotist, and the hypnotized_dom.

If there is a page break (different post entirely, but can be within the same series), the female from then on is a femsub, and the male becomes maledom.
If there is a panel break (same page of a comic, different picture), I'd argue that femdom, femsub, maledom and malesub all apply.
If there's no page- or panel break (aka a single picture with text next to it or the like), femdom and malesub stay what they are. Then the tags hypnotized_hypnotist and hypnotized_dom get added, like I said before. (This is a lot, right? :P)

An example of <<hypnohub.net/post/show/11...trix-femdom-femsub-finger|hypnotized_dom without hypnotized_hypnotist>>, and an example of <<hypnohub.net/post/show/39...y_-averyshadydolphin-comi|hypnotized_hypnotist without hypnotized_dom>>.

I'll be honest, I did have a look at the hypnotized_dom tag because of this post :) you can hit the little "?" to the left of any tag to be taken to a page with a definition and some popular pictures with that tag. It's not 100% fool-proof, but it helps!
