I don't give him a reason to lie, especially about that so I would be irritated he lied about something he doesn't need to.

i hope my Partner knows that i wouldn't care if She was watching porn. i especially hope She knows because Wwe've talked about it on numerous occasions! If She did lie about this, i'd be more concerned than anything because it would suggest a major gap in our communication and understanding or something deeper going on. Sounds like they had some kind of communication breakdown somewhere along the line, or she gave him some reason to lie somehow. Seems like she probably, intentionally or not, gave the message that she wouldn't like it if he watched it and so he said what he thought would please her at the time. If no message was telegraphed in any way on her part, maybe he has some shame regarding his porn habit. Either way, it's something that they should probably talk about rather than getting upset or angry.

Bless her heart! Hell yes I'd be upset! Porn is absolutely hated by my partner and I. I have a big problem with it, not an addiction problem, a problem as in I f'n despise it. I hate that it contributes to so many hurting people.

Anyways, obviously porn is a total deal breaker for me. I'd just as soon live happily unmarried and alone with my cats before I even considered a man who had any interest in pornography. I am better than that, I deserve far better and well, I just happen to be one of those women who won't settle for any less.

How a person handles this situation is the most important though. I hope your sister is doing okay though. I'm sorry she's hurting. I know many people see it as petty, but nothing is petty about a hurt heart, and if it hurts, it hurts! You can't help what hurts. While some people may have no problem with pornography being a part of their marriage/relationship, some do and both types should be accepted.

Like I said, I'd be hurt. I HAVE been hurt by pornography. Devastated. Traumatized, in fact. Of course not by pornography's existance alone, but by a person and pornography combined and how they chose to use it to steal, destroy & use me.

Thankfully, the topic of pornography and everything else that would and would not be tolerated by me or my partner was addressed in the very beginning of our relationship. We've been together for 6 years and are stritcly monogamous, and actually totally happy that way. That's okay too! If it so happened that during our beginning times, he expressed diff. views than me on what monogamy is (in our opinion, monogamy is being ONLY for/with each other in every way, and pornography is not part of a monogamous rel.) I'd have turned around to never look back. Most people would think that's crazy, but it's served me & my heart very well.

Now, it'd be really different to have my partner make me believe he was trustworthy and did share the same strong views as I do on pornography, only to go and betray me later on. That is hurtful. That is enough to really do some damage, and it should not be tolerated. Lying is never okay, and you don't lie over something that you know would negatively affect the person you "love."

I hope your sister is able to move past this for her own sake. I hope she chooses what will ultimately make her happiest, and nothing less.

I've been lied to about some things. When you lie about something that a person feels so strongly about, it has devastating affects. I don't know how your sis feels about the use of pornography, but clearly it must have upset her. If someone ever isn't okay with something, they are never wrong to say and to not settle.

Wishing her the best.

..."or she gave him some reason to lie somehow." This I have to kindly disagree about. I feel a lie (no matter what it is over) is never justifiable, and never ever someone else's fault. Showing you're opposed to something is not a reason to lie. There's no excuse for lying. Never.

You need to pick and choose your battles, besides when you're in a relationship everything should be open and honest. There should be no reason to hide anything or lie. I personally let my man watch porn, go to nudy bars etc with or without me.

Often setting unreasonable demands is setting one up to be lied to.

That's something along the lines of what I was going to say. If she made him feel like he needed to lie about it, than the issue is less of a concern, but if he was just lying about it, than it would be an issue.

Really? How about if you weren't feeling quite as attractive as usual but your lover told you that you looked beautiful nevertheless?
We all tell little lies every day.

Oh and btw you should have used "it's" rather than its.
It's = It is
It's = It has (not possessive)
Its indicates possessive.

Yes, I think this is the main thing.
