It would all depend on the type of Entertainment they wanted to watch. I mean there are tons of different types of Adult films on the market now a days. It would also depend on how often they wanted to watch it.
My personal opinion is that some Adult films can be educational and a assistance to spicing up the love making. A lot of the main stream stuff that is out I find extremely degrading and some times brutal twords women so that would offencive to me. There are many films out there that are couples films. There are also a lot of strange fetish films out there too that would not be ok with me.

Depends. Watching it with me, without me, how often, what kind, why, etc?

Lot of variables to consider before I'd say I'm not ok with it or it's not a big deal.

I think pornography is like alcohol or gambling or smoking or any other bad habit. In small doses its destructive power is limited, but in larger quantities it can destroy relationships and lives. Some couples use pornography to enhance their sex life, but it can also have the opposite effect if one or both partners are caught up in the fantasy and neglect what's real.

I don't personally like it mainly because I think it's sad..... Yes it can turn people on however I think of the people in the films..(does that sound preachy) I don't mean for it to...
I would be really bothered a lot if my child for instance was in one... On top of that safe sex is never practiced in these films and I have no doubt that there's been a lot of disease passed within this industry ....To each his own though

If people want to make their own films for their own relationship I think that is something else again and why not!

It seems to be "a guy thing" more than a ladies thing. I can deal with it as a once=in-a-while diversion, but wouldn't want to make a steady thing of it.

Sure. And I'd tell them I want to watch too. Might give me some pointers on new techniques. But I'm a guy.

Porn can be very addicting for men. As they increase their usage, it can lead to compulsively viewing porn at work (and getting fired for it, this happened to a co-worker of mine back in the 1990s), attempting to initiate real-life contact with the underage porn actress, resulting in the porn addict becoming a registered sex offender (happened to a former neighbor of mine), and it can lead to the porn addict becoming abusive to his female partner, since intimacy with his real-life partner becomes less satisfying than the fantasy world of porn.

Adult entertainment such as strip clubs/porn?

No, I wouldn’t be okay with it. Personally, I don’t judge others that chooses to do so but for myself personally it's a deal breaker.

I feel that once you open up the Pandora's box at the beginning of a new relationship without fully knowing each other then it could turn out disastrous and there is no turning back. If you enjoy adult entertainment yourself then watching it together wouldn't be a problem. But do it because it's your decision, not to please a new partner.

Sex should be exciting and an act of pure bliss. There are other ways to spice up your sex life.

I personally don't see it as a big deal. But like everyone already stated, it depends on how often, with or with out me? For me, he does watch it with out me, at least he used to, I don't think he does anymore. Now we occasionally watch it together and its great. It's like foreplay before the foreplay.

I see it being a problem if it was him watching some weird fetish type of stuff or watching it but neglecting me.

I also think it is not a problem. However, I would be curious to know what exactly draws them to it... If I found out that my man likes trannies, gay porn, rape-like videos, gagging or really freaky violent sex, I would probably not date him anymore .

I agree with majority of the above opinions.
I've heard the argument before that "all men do that," be it watch porn, go to strip clubs, etc.
But like mostly anything, "everyone" does not do it.
I think what is most important is for both people in the relationship to communicate honestly about what they want to do, like to do/watch, etc, and come to some sort of mutual understanding.
It definitely can be a slippery slope and a source for consuming addiction for some, men or women.
I also am personally someone who thinks that in certain cases, strip clubs and porn contribute to skewed views and stereotypes of women. Not in all cases, but in some.
As with most things, being honest and open with a potential partner is the best policy, to avoid damage to the relationship.

When I was married to my first husband I was uncomfortable with it, but read similar things that are posted above so I figured it was normal. Now after what I've been through, I would say I would not be okay with it and would probably break off the relationship. I'm not going down that road again....ever

I have to add to my previous post on here about it. I have heard over the years also that all men do it. I would say the majority of men probably do watch porn from time to time. I have also learned both from talking with male friends and experience in my own life that men will watch adult movies from time to time, but the frequency picks up if they are unsatisfied with either their performance or the level of attention they receive from their partner. Honestly I am guilt of watching adult movies, but have not been to a strip club since I was in my early 20s and single. I have no desire to go to any of them when in a relationship and the adult movie watching, becomes vary rare. There are some really good films that can be educational if you watch them with an open mind and don't let hang ups decide your actions. I am dead serious when I say I think most of the mainstream adult film is extremely degrading to women. I cant stand anything with brutality (choking, slapping) and I am repulsed by most of the fetish ones. I have always been in the mindset that it is making love and not just sex. Even if it gets pretty wild the emotion is still there and there is never any intent to make your partner feel uncomfortable or hurt them in any way.

When I gave my answer above, it was in the context of how so much depends on certain factors before I'd consider it, not as someone who gets into porn, but as a partner. I actually don't like porn, myself. If my husband wanted to watch it with me, I'd consider it but I'd have to be very clear on his intentions, though it would be hard for me because I agree with one of the comments that it feels sad to me.

And I don't think it's just degrading to women. It's degrading to men too, if you really just think through what is taking place on film, whether hardcore or not. I'm not saying this as a prude. I'm saying this as thinking about people who find themselves, and who kid themselves into, thinking such a personal, private act performed on camera, or working in a strip club, is somehow empowering or owning their sexuality. Those are the lies people tell themselves to deal with the fact that this is what they are doing for a living.

I think for people in the industry, it does skew their views on sex and relationships. Which means for people watching porn or going to strip clubs, it then kind of skews their view of sex and relationships too.

Anyway, You have to do and think about what you're comfortable with. If you don't want your partner watching porn, that's ok. If you don't mind, that's ok too.
