1) A) No. it's not really physically possible for it to go that far up. Barring major abnormalities, our innards aren't really made for that, and neither are the cups. If anything, you might find that the stems/handles are too long and you might want to cut them shorter. B) Periods are messy, bodies are clumsy. It can be messy, or you might get the hang of it/it works super well for your body and it's no mess at all. C) No, no vacuum effect. There's a few teeny tiny holes near the top of the cup and a vacuum isn't really possible. Or if it is, it's weak/negligible.
2) It has a little handle/stem. I hold tight to that, right up at the base, and twist it around. Pops right back in shape.
3) This varies from person to person, it depends on your flow and the size of the cup. I've left it in for a full day on multiple occasions, having forgotten that I'm even on my period. It's been a while since I've had heavy days...I do remember being able to "feel" when it was getting full though. I have absolutely no way to explain it. Initially I was paranoid that it was full and I didn't know, and I'd go to empty it and there'd be hardly anything there. Then eventually I learned what "full" felt like, and I can't explain, it just feels full. You will know.
4) Doesn't hurt to, but it's not necessary. I usually don't, but every now and then I forget to make sure it popped back into shape, and so it leaks a little. If it's inserted correctly/is a good fit, your underwear should be safe.
5) Heartily in favor.
More thoughts: There are loads of different cups, in different shapes(wider, deeper, longer stem) colors, materials (firmer or more flexible), sizes (larger if you're given birth/abortion/are over 30). IIRC they're not cheap. Picking one is a straight up gamble, and I expect it would be very discouraging if the first one you tried was really uncomfortable or awkward. Diva Cup was the first one I tried, and I loved it. I usually forget that I'm on my period when I have it in. Like, we'll start getting down to Teh Sexy Sexin', and I'll be like, "lol whoops, I'm already occupied, brb."
The easiest way to insert/empty it is in the shower. It will spill, and you'll be all, "holy shit someone was totally murdered in here," but it'll rinse away effortlessly because that's how showers work. Emptying it on the toilet it not quite as easy. You have to pull it out without tipping it, then tip it over, and then slip it right back in. I never found it difficult, but I do still prefer the shower. I just like being able to rinse it before reinserting. Also, I grip it very carefully and very tightly, because (in that moment) I can't imagine anything grosser than dropping the cup in the toilet or on the ground. So far, I've never dropped it.
