oomis – “I might want to eat a cheeseburger, but it is forbidden to me. So even though I smell that wonderful odor wafting from MacDonald’s, I am NOT going in there, even if I am RAVENOUS because I have not eaten all day. A little self-control goes a long way.”
The difference is, taiva for a treifus is ok. Taiva for arayos is not ok.
And I know how I would feel if my spouse said “I might want to lay with that man/woman, but it is forbidden to me. So even though I see that wonderful person/desire that wonderful person etc., I am NOT going to do it, even if I am DYING for him/her. A little self-control goes a long way.” That would be the end of our married life.
