Yes, it can. As Jim above says, it can distort your reality.
I am female and had a boyfriend who constantly wanted to know why I didn't look like the porn stars. I had to tell him, hey! Those are super good looking women who are chosen especially, the make up is over the top, the editing is always to make the stars look good and NO woman I know, goes...OOOOOOOhhhhh aaaaaaaaaaah...having things shoved up them the way they do. In fact, I have watched tons of porn and can tell you, it is acting on the women's behalf.
In reality a woman doesn't go, Oh hello, you have a big **** let's ****! (ok there may be a few out there, but they are usually drunk!) Then she does not automatically go into moan groan mode the second he touches her breast or other anatomy!
It's great to watch porn as a stress reliever or if you don't have a partner. No one says it is wrong! BUT, do NOT believe that is how a real life woman wants to be treated. Keep the porn to your own fantasies, but learn the art of seducing and pleasing a woman. A woman takes time to be aroused, and if you just do the wham-bam-thank-you-ma'am thing, like in porn movies, you will be all by yourself in no time, watching that porn and pleasing Mrs.Palmer and her five daughters!
It can...you must recognize that porn is not real...most are not real lovers and are being paid to have sex with each other...there are no emotions involved..they show up..take their clothes off may shower get on the bed (or whatever they're using) do the usual routine, shower and go home. The women make stick around for a few more shoots as will the men..the men frequently have trouble getting/keeping erections so there are fluffers..women who's function is to keep them hard with hand work or oral sex. and you will find many of them into drugs who hate their work and some who wind up killing themselves.
If you maturbate a lot while watching porn, you may find yourself having difficulty having an orgasm mainaining an erection, becuase your are used to your hand...you may find yourself comparing your partnter to the women you have seen on porn or even fantasizing about them...
God made the female body to be admired and treated the like the beautiful thing that it is and to be loved and adored by us men who love them...get rid of the porn and focus on how you can make your partner feel you care about her and love her body as it was meant to be loved....not trashed by these porn stars who could care less about the women they have sex with;
