Do all men do this???

Well, I don't do it, so no. Not all men do it.

It's not normal to do it to that degree. Your husband has serious issues.

I can't say i look at porn every single time i am on my phone, but definitely often. I share porn pics often with a buddy of mine via text. I will just randomly send him a pic of some hot chick with her legs spread wide.

The girls put up all the pics first. They get off having 10,000 likes and showing screen shots to their girl friends.

Yes, your husband had a porn addiction, and that is why he isn't having sex with you. For a change to occur, he needs to recognize that what he is doing is morally wrong before God, he needs to ask Jesus into his life, he needs to submit to counseling, and he needs your help to keep him away from computers and the internet. The truth is this can destroy his family, his career, and his soul. If he is unwilling to listen to your feelings on this matter, he definitely has serious problems. I struggled with pornography, I still do from time to time, but I would never use my wife's phone for it, or her computer. In fact, I personally don't store any pornography. And I experienced that after a month or two of going clean, my sexual life with my wife became normal once again.

How dare he said all men are like this . Speaking of myself i search for women photos or videos once in a month for it is like watching flowers or watching peacocks .

He may have a porn addiction which is not healthy

The hubby is a serious porn addict, leaving a trail for everyone to know. Give it time, eventually he will do something will cause him to lose his job.
Demand he get help and check in with you frequently or pack your bags and get the hell out.

Is the issue the porn or your lack of sex with him? It sounds like he's sending you a message. If he's looking at porn instead of having sex with you, you both have a problem. Some men watch a lot of porn to stimulate their appetite for their wives, so that could be normal too.

If he was getting what he wanted in real life he wouldn't be looking for it elsewhere. If you're being stingy with the sex be glad he isn't seeking the real thing elsewhere.

Apparently, internet porn is extremely addictive. Sounds like hubby has a very serious case of this. All men do not do this; hell I don't even know what instagram is.
If I was you, I tell him to get his own damn phone and not let him near yours. Then you'll have to decide if this is really a big deal to you and whether you want to deal with it or ignore it. There are therapists who can help.

Maybe he isn't getting enough

It's normal for a majority of men to look at porn. It's abnormal for your husband to look at it obsessively, he needs to learn moderation.

I think it's disrespectful for him to do that on your phone.

I can't speak for all men but I think it's entirely normal for most guys to enjoy looking at partially naked women. It's programmed into us for the propagation of the species.

I think of sex as being a spectator sport as well as a participator sport, much like watching a ball game or an Olympic event. How did it ever come to be called "porn" to imply that it's evil and that people who watch it are bad? Is it because of the Judeo-Christian ethic that sex outside of marriage and/or for pleasure instead of procreation is a sin?

I wouldn't use somebody else's phone to look at porn. I wouldn't want most people to know that I enjoy looking at porn, or what kind I like.

Yeah pretty much and you had do something about it fast. Rarely do i advocate a woman "putting her foot down"
