No, of course not.

Absolutely not. That is laughable.

Yes, if you're sitting an exam on said smut/romance novel and you take it into the exam room with you, that is cheating.!

no but I highly believe everyone’s boundaries are personal and to be discussed in the relationship. and all boundaries are valid. if someone is against them, they aren’t the right person for you.

No but I think if you have a partner you talk to them about it - perhaps to aid stimulation or they can understand fantasies.

No. That's as far from cheating as possible

personally no, but it really depends, only the people in the relationship can say what's cool and what's not cool in that relationship...I guess you have to ask yourself questions like, would I do this in front of my partner? How would they feel about me doing this? That should guide one's decision-making

I don't think so. But it seems that your idea of cheating is totally different from the usual meaning of the term, so in your mind it might be cheating while it isn't cheating from the pov of others.

No, I would need something to spice up my relationship (I'm cold as heck).
