Oh, there's another thread by Abaya, and one by *Nikki*, I just can't find them right now.... Arggh!
1. Yes, it does stay without any issue.
2. Not when we had sex, but with fingers, yes.
3. Other stuff... this one is supposed to be pretty good, as it's supposed to give you the lowest, most steady dose of hormones necessary. However, the concepts are exactly the same. See
this post for more info. That's a great info-heavy thread altogether.
Basically, if you're okay on hormonal BC in general, the ring will probably be fine. If you have other issues - headaches etc., keep an eye on them, they don't necessarily get better on the ring. Without knowing why you were not happy with the other BC, or what kind it was... can't tell you more than that. Hope that helps!
