Yes, you keep saying this. I don’t think people care much about whether you personally think you’re sinning, but rather, you’re saying it’s objectively a sin.
I.e. If your wife turns you down for a trivial reason, she is sinning. If a person turns their spouse down for a trivial reason, they are sinning.
And honestly, wanting to unwind doesn’t necessarily mean that person has fatigue to be quite honest. Unless you have a very loose definition of fatigue from what I guessed (I.e something other than ‘extreme’ tiredness).
But if she is sure I have no reasonable cause to refuse, then her request is, by definition , reasonable.
Not necessarily? Someone may have a less than pure intention (lust) for sex without the other knowing. While a request for sex isn’t assault, it can be manipulative for someone to keep asking for sex knowing the other will say yes out of guilt even if they don’t personally want to.
I think GospelofMatthew may be describing a scenario where someone is pressuring the other for sex, knowing that the person won’t say no even if he/she wants to. E.g. Even after your wife said no, and you know she doesn’t have your idea of a good reason so you keep asking her knowing that she would feel guilty and eventually give in
Or maybe that example you gave where the husband comes back and asks for sex again even though he initially said yes to her request for postponing. The wife in that situation would now feel pressured because she doesn’t want to sin.
