If I interpret the OP correctly, she’s not suggesting doing it as any kind of a moral stance, but as kind of the sexual equivalent of saving up an appetite for Thanksgiving dinner.
I don’t think it would make the eventual connubial event any better, but it might make it shorter (at least on the first go).
God, I hope my fiancee reads this thread. She’s been quietly muttering about doing this to make the wedding more special, and I’ve been quietly murmuring supportive noises while clenching my fists behind my back in impotent rage.
…so to speak. (Uh, but seriously, were you planning on going along with this while resenting it but not saying anything about it? 'Cause that sounds like a pretty bad idea in its own right.)
You don’t want to know where I thought this was going.
I agree with this.
We didn’t do anything like this before we got married, but the wedding night was pretty awesome anyway. We were both really happy and excited, which is all that was really needed for a “special” wedding night, really.
I don’t think I’d want to spend my wedding thinking “I finally get to have sex again!”
Here’s a thought: begin your married life by communicating honestly.
As others have said, you may be too exhausted to even have sex on your wedding night (or at least to enjoy it), so don’t count on it being super duper special and setting the bar for the rest of your married sex life.
On the other hand, I know some people, particularly women, who have found that they actually benefit from periods of abstinence while in relationships (e.g. if they’re traveling). If the sex is normally great, not getting it drives them wild, physically and psychologically. If you’re one of those people who can orgasm more easily when you take a break, maybe you could mention this to your fiancé and agree on a week or two of abstinence, pre-wedding. Though it really should be a mutual agreement. ‘Cutting him off’ sounds a bit too much like you’re planning on giving him your precious lady blossom or bleeding on the sheets on the wedding night.
Man, people are being rather rude to the OP. The only concern that I see is “I’m considering cutting off sex”. It definitely should be something that you and your fiance discuss.
My friend and her now-husband did exactly this, but both of them wanted to. They wanted to build the anticipation up for that First Married Night, even though they hadn’t been exactly chaste before that. 
Since they were both on board and it was for a reason like that, I thought it was kinda sweet.
Welcome to marriage.
Ha! Good one.
It seems to me like the OP wants to do this just for the sake of doing this. Sounds like a good way to piss the guy off.
Why? Do you feel unable to speak your mind about this rather than bottling up your frustration and being passively angry or finding some indirect way to get back at her? Why not just talk directly about your frustration with her, or if you can’t do that, e-mail her a link to this thread and explain that you share the general opinion of this idea.

I guess I shoulda used a winky smiley or something. I was just kidding. She did actually bring it up, and I said, “what’s the point?” and upon further consideration she realized there wasn’t one.
Well, I like the idea! Sort of a preview of the rest of your married life…
Yeah, I wouldn’t be happy about it if I was the guy. I’d suggest the OP reconsider.
My wife and I actually did this for a month or six weeks before our wedding, and it did help make our wedding night special. It was, however, a mutual decision.
As long as both of you are on the same page, why not? Abstinence makes the heart grow fonder…
I’ve talked to my fiancee about doing just that and we probably still will. She and I jumped into sex rather quickly into our relationship. One of the reasons I wanted to hold off of sex until marraqige because it would force us to be romantic and caring even though we would both know that sex is off the table, we’d be intimate but not physical.
But yeah, talk to your fiance first. If he is ok with it and it is something you feel strongly about, go for it. It is your relationship.
Words fail me.
Why not do a different but similar thing? Like, no three ways until after the ceremony. Or, no bestiality until after.
Not that I’m a fan, particularly with the unilateral “cut him off” language, but I did think of one possible rational motivation.
It is likely that marriage will include some times when sex is not feasible (as mentioned, kids, illness, business travel, etc.). If one party has doubts about the marriage’s ability to weather a dry spell, it might make sense to test that out before deciding to get married. This isn’t the same as the saving up appetite for Thanksgiving dinner idea, and would make a lot more sense before the wedding was in the active planning stage. Still, like so many things, it would be better to find out before rather than after the big commitment.
