<human>: It started out with little lies about nothing really. For example, he would lie about wanting to get off the phone because he was going to bed when he was really going to the bar with his friend. Then the lies started getting slightly bigger, like lying about having the day off from work because he wanted a guys day with his friend. Then fast forward to now, when he has promised me that he would stop watching porn (because I feel that he cannot maintain an erection with me) and I have now confronted him 6 different times and every time, he will first deny it, then get pissed off at me for confronting him, calms down and will admit after I press the issue and then he renews his promise to abstain. 

I don't like to think I am being unreasonable but I can admit that its a bit unrealistic to ask him to completely abstain. I want our sex life to be as important to him as it is to me, and I feel like he doesn't think losing an erection is a problem. Another thing is frequency, I'd like to have sex a few times a week, and I would like to not be the only party initiating. He is okay with having sex once a week (probably because of his porn habit) and he claims that he initiates all the time. 

I don't know what to do. With him breaking the same promise over and over again I have a really hard time believing it wont happen again. I've asked him why he feels like he needs to lie to me and he has always maintained that he doesn't want to disappoint me or make me sad, when really most of the time I don't care if he wants a guys night or if he wants to do just about anything. The porn thing is really the only thing I have put my foot down on. This last confrontation he has declared that this time will be different, that he wants this relationship to work and that is why he won't watch porn anymore.

How do I trust him again and move forward?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: BF promises over and over to not watch porn due to semi ED issues but breaks promise every time and I still want to trust him but don't know how.
