My mistake, let me recalibrate:
Of course it isn't, when you have a family to take care of, or a job to hold, or studying to get the job of your dreams, sex is no comparison, you can sacrifice it.
But you need to understand, between all those things, for men, there's sex, and that means alot...a man who wants sex from his wife but doesn't get any is hard, when whatever turns you on has to be subdued with self-gratification. It's *sort* of, saying to a lovesick woman "you will never ever have love". You can live without it, but really, it gets to you when it's always on your mind. (Some people will understand what I'm saying here, others won't)
And don't forget, some men have less to no desire for sex, that could be your situation.
I should've been more clear, my posts are sometimes very vague because I expect everyone to understand me because of how I think, wich isn't the case.
Hopes that clears the message I couldn't perfectly explain.
