I went to my local health food store, and got a Diva, size 1. Im 18, a virgin, and I absolutely love it.
I hadn't really read much of this community in regards to newbies/virgins, and didn't really do the baby step thing. I bought it, cleaned it, and inserted it.
Here are my experiences thus far:
I put it in, it opened right away and was fine. I went and did house work, yard work, and basic lounging around and couldn't even tell that I had it in. Seriously, didn't feel it at all.
Took a shower about 4-5 hours later, removed it for the first time, and it was super easy. I had been really worried about removing it, because it had migrated pretty far up there, and I had a brief moment of panic. Once I calmed myself down, it was easy and there was no splattering whatsoever.
I'm getting ready for bed now, again, about 4 hours later, and that was the real test: if I could remove it to empty it outside of the shower, without making the bathroom look like a murder scene. I had no problem. I removed it, emptied it, rinsed it, and reinserted it within two minutes.
The ease of use may have been because I have always used tampons, have the ability to relax on demand, and have a heavy, heavy flow, which made things fairly well lubricated. (not to be crude)
I will edit this post tomorrow morning, with my overnight experience- if it doesn't leak, I will be the happiest woman in the world.
