I know the definition of suction of course, but I just need clarification on what this means during the removal process. I just got an IUD, and I don't want to stop using my cup. The problem is, my cup always sits so high that I have no choice but to barely reach the stem of the Lunette (very long stem, mind you) and slowly pull it out. My finger comes nowhere near the edge without doing this for me to break the suction. I can only break the suction once I've already pulled it quite a ways down. 

I should note that I previously used the Diva Cup until I lost it (yeah, I don't know how I lost it but I did!) and I don't remember it sitting as high as the Lunette did. I'm pretty sure the Lunette is longer than the Diva though, just going off of how I remember them looking, so that makes no sense.

So is the process of pulling it down by the stem creating a suction? Is that what could suck the IUD out?

The Lunette is 47 mm long for the smaller size, and about 53mm long (52?) for the larger size. Both Divas are 57 mm long. That is not including the stem, which is much shorter on the Diva. Still the Diva is the longest cup on the market, but overall the stem of the Lunette may give it a few extra mms. Width can also make a cup sit higher, I think. So you might be better off with a large Diva than a large Lunette.

Afaiu, not having a high cervix, suction is what happens when I wear plastic disposable gloves to dye my hair, and I try removing them by pulling at the end of my fingers, especially if my hands are wet inside. the glove stretches but DOES NOT come off. An uncomfortable feeling ensues, until I remember to get air inside the gloves by lifting them up near my wrists and palms. Then there's no more suction.

This is also how I remove my cup, by inserting a finger next to it and introduce air between the cup and my vag. Others have described a bad suction effect as giving your cervix a hickey. Basically, if you feel resistance, don't pull harder. And in your case especially, bear down a lot ! like you were trying to give birth to your cup.

I suppose suction could dislodge an IUD, so could if you accidentally pull the strings. Especially if you're prone to expulsion in the first place. But it shouldn't be that easy. An IUD is surprisingly large.

The first time I tried a cup, I panicked and YANKED the cup out without breaking the seal. YYYOUCH! It felt like I'd given my cervix a hickey! If that didn't dislodge my coil, nothing cup-related will!!!

Thinking about IUDs, their shape and where they sit, it sounds very unlikely to me that suction, applied to the cervix, could suck it out. After all, suction can only really pull on something that is pretty much closing off a tube-shaped space, or it would have to be very very strong, and the cup can't create that much suction even if you'd pull it out without breaking the seal. That's what the holes are for.

I just can't see it happening. I think that people who pull their IUDs out by accident generally do this by pulling on the string.
