There are two kinds of sex issues in a relationship:
1) when the couple is having non-bedroom difficulties and sex becomes a sort of afterthought because of said issues; or
2) when one person is more or less bored with the other and lacks desire for sex from their mate.
Given the fact that your dude actually lied to you and said that sex isn't that important (and let's be clear, that was a lie) I'm guessing that option 2 is the culprit here. Perhaps he still loves you but isn't in love with you anymore and doesn't see you in a physical light. Which means that he (and you, by default) is just going through the motions until you all unceremoniously say your goodbyes.
Because that's coming. Look, for any real grown-up relationship, sex is a part of it. Now there are likely to be droughts when issues need resolving and for some reason, sex just becomes difficult, but you didn't say you were beefing, you just said that your man said sex isn't that important.
Now, you just might be boring (and I'm going to assume you meant in the bedroom). However, if he really loved you and wanted to be with you, he'd suggest some ways to liven up the boom boom room ruckus. And if you still sucked after that (no pun intended) then he'd have a sexual compatibility reason to pull the plug (maybe not a great reason, but a reason nonetheless). Plus, no man is going to give up the "release" for good. He's probably beating himself off right now in the other room to some busty Brazilian babe offering herself up for free on the Internet.
The bottom line is that sex is part of the reason a lot of us get into relationships, a hopefully endless supply of booty. Hell, some of us even argue just to have angry sex. It's just what humans do. I'd bet that right now, half the people reading this would rather be having sex but they're at work and can't touch themselves without it looking wildly inappropriate. Plus if you add the whole cubicle thing, it gets downright disturbing.
A lustless relationship is one that's bound to crumble under the big booty elephant in the room. Plus, I'm guessing YOU want sex so nobody is getting their basic human needs met.
My suggestion is that you talk to your dude and ask for blunt honesty. Maybe the real problem is something that you two can work at, maybe not.
But there's only so many pr0n sites out there (not true, it seems like a new one pops up - no pun intended - everyday) and there's only so far laptop love can take you. Every now and then, you really do need some skin-on-skin action.

Boom boom room ruckus?! lmao. yep, that's just been added to my lexicon.
I agree though - she should approach him with the swiftness and find out what's going on, no Marvin Gaye. And if he's over it, then move on. More fish in the sea, and all that jazz.
Honey you need to spice up the sex. Here's what I do, sometimes I talk in a really creepy Russian accent and pretent that I'm about to beat him sensless with my skills at hunting rabbits and squirrls in the forest with only my bare hands and teeth.
Or I pretend to be a notoriously violent Canadian named Joy.
Either way, it gets him in the mood really quick.
Or you need to start giving oral or demanding oral from him.
