The main purpose of porn is to facilitate masturbation. And since men are very visual animals, torrid depictions of humans in the midst of the love act do help them get to the big "O" sooner. And I got news for ya, Sis, when men masturbate they're not always thinking about you. Such fantasy scenarios are normal and very common. In contrast, many conservative parents would rather their children witness a graphic depiction of violence on screen than subject their progeny to the sight of a bum or a breast. As a society, we still harbor some fairly Victorian ideas when it comes to what we call healthy sex. Let your young buck wank and spank to his cock's delight. I'll bet money he has plenty left over for you. Honestly, your prehistoric attitudes towards porn and masturbation rank among the least of your problems.
These trust issues--or obvious lack thereof--are gonna tear you guys apart. You eagerly search for tiny deceptions and betray a distrusting approach to your man. Maybe all his "little lies" represent a strategy for dealing with your jealousy. You're freaking out over the way your man pleasures himself, which frankly is his own business until it makes you late for the movies. If you want to spice things up, try and get him to wait until you get home from work. Tell him you care enough to lend a helping hand. Frankly, If men could have multiple orgasms, they'd never go outside. Involve yourself in his pleasure rather than look for ways to make him feel ashamed for not sharing your specific views on self love.
You ask about female employees at his job as if he were a stray dog drooling over a smoked neck bone. If you were pestering me about enjoying the very porn that we just rented together, I'd start feeling repressed by your ancient attitudes towards sex. If you constantly asked me questions to sniff out whether or not there's even the slightest possibility that I might cheat on you, I'd probably tell "little lies" just to give myself some peace from your interrogations. If you continued to distrust me and make me feel like a cheater, I'd probably cheat on you just to hasten the end of this angry, distrustful relationship. Reign in your jealousy and quit trying to beat down your partner for the way he beats off, or you'll create a liein', cheatin' spank beastie who can't wait to get away from you. If your man wanted constant ridicule, he'd go back to living with his mom!
