I want to hear your opinion

This is about Nsfw artist or r34 artist, masterbating to things, and erotic thing

i was going through Twitter,reddit and pinterest to see art of things I thought where cool but sometimes I see accounts of girls and boys who draw Nsfw of things/r34/hentai of things like tv shows,movies, anime,game,etc

So I just want to know if any of the women and men who draw that could be Christian and if so is it okay to to see,read watch, or draw NSFW things if your in a relationship or not I don't think it that bad in my opinion and if you don't masterbate to it is it ok.

Next question is it ok to masterbate to porn hentai etc and not be addicted to like you do it once in a while I curious because their are many men and women who do this or people who do it everyday.

And is erotic thing ok? let's say your wife or girlfriend or you are very freaky you or they like to read,draw,do erotic things sometimes or has (things for the bed room) that you or they use rarely or sometimes and is that ok.
