What are the limits to fidelity?
Firstly, this is not a “I’ve got this friend who…” question though the more I protest that, the less anyone will believe it. I’m not disinterested though, since I’m human, male and have been married for 18 months. Given an imagination, not to mention all the tales or cliches one hears, I’m capable of foreseeing many possible futures, about which I’m curious. For the most part, I’m just interested in peoples’ views on how to resolve the complicated mix of love, security, animal lust/physical needs and differing tastes.
So where does a duty to fidelity end? If one or both parties lose interest, it may be down to relationship problems that are either resolvable or irresolvable, or it may be down to mundanity. In the latter case, it may be solved by a bit of spicing it up or it may just be the way things are after many years.
And what of tastes? Are there activities/fantasies (let your imagination run riot) that one party might wish to experience at some point in their life which the other party has no interest in, that could justify seeking them out elsewhere? Would there be a moral distinction if you paid for it? At a very basic level, what if either party wasn’t into oral sex - thankfully not the case here though I have heard such people exist. Would that mean a life without head?
What would a loving, caring husband several years in, facing the prospect of a minimal or non existent sex life do? I imagine every individual’s answer would be different - but I don’t imagine it’s a cut and dry moral issue. How many people could say - “I love you, want to spend my life with you but don’t want to have sex with you and understand if get it elsewhere,”?
On one level, marriage is a promise, agreement, contract - infidelity is clearly breaking that promise (we may assume that breaking promises is usually wrong).
On another, no loving spouse would wish to harm their partner and a rational actor would not wish to endanger an otherwise healthy relationship for the sake of a roll in the hay.
Is taking part in sex as much a part of the contract as not being unfaithful?
I guess, when it comes around, family trumps most of the other self-interested issues, if the relationship is fundamentally healthy.
