Give me strength... the replies on this thread. Is the bar really so low that we're defending a man's lying and porn use while he tells his partner that she can't masturbate and use sex toys herself? Really?
OP, I'm aware this is an old thread now, but I hope you aren't still with this hypocrite? It is completely fine to have a boundary against porn use in your relationships. Don't listen to anyone who bleats on about men's right to watch whatever they want or about how every man does it - this is bullshit nonsense.
Men who value their sex lives with their partners (and their own sexual functioning) try to steer clear of porn, particularly when they're in a committed relationship. Many women regard porn as a form of cheating, and that is completely fine. You are not alone in your boundaries and please do not allow anyone on MN to tell you otherwise - many women have to convince themselves to be ok with porn, and that everyone uses it, to justify tolerating their own DP/DH porn habit. (Or they genuinely don't mind because they don't want a sex life with their DP/DH anymore anyway - everyone brings their own viewpoint into their answers and these threads are often very triggering for people with their own sexual dysfunctions...)
Some people are fine with porn use in the same way that some people are fine with polygamy - the key is both partners are honest with each other and boundaries within the relationship are agreed upon and upheld.
In other cases, having sex with others whilst lying about it is cheating, and using porn whilst lying about it is also cheating. Not everyone wants third parties involved in their relationship (digitally or otherwise) and that is a perfectly reasonable expectation in a monogamous relationship - it is not controlling to expect your partner to be sexually faithful to you.
However, telling your partner not to masturbate whilst masturbating yourself... that is controlling. Control is all about unbalanced power dynamics. And it sounds very much like, in this relationship, the power balance has been heavily stacked against you - his double standards and lying are the problem, not you.
