I have been playing guitar on stage for forty years, and with long nails for about eight years now. It takes a lot of practice, adjusting your style, and some guitar and strap mods.
My nails are gel, about 1/8 inch past my finger tips. I ask my nail lady for 'sporty round', and she knows the length. In order to play consistently well, you nails MUST stay exactly the same length all the time. You'll never figure it out if you let them grow for ten days, then trim them back.
Raise you guitar strap. Don't reach around the guitar neck no matter how cool it looks. You should be approaching it with a relatively straight wrist, from below.
When bending a note, don't try to push the strings above it out of the way, let them slide over your nail. This will wreak havoc on the polish, and takes some practice. If you're playing really fast, or long runs, tilt your whole hand so you nails point a little more parallel to the strings.
I play really fast country, with a bend on almost every note, or some times bending two strings at once, by different intervals too! I use a Fender telecaster with a B-bender. By simply pushing down on the neck, the B string raises a full step, allowing my fingers to bend another note simultainiously.
If you get serious about it, have a good luthier install some taller frets. I like Dunlopp 6105. This is a 3-5 hundred dollar job. They are much easier to play with nails, but require a light touch to stay in tune.
By second set my nail polish is toast. Get your pictures taken before it looks like a beaver has been chewing at your manicure.
This is pretty advanced, but I hope it helps a bit.
If I play guitar in a music store, or some place the audience is right up close, people don't ask how a girl can play like Brad Paisley (or similar, he's god), they ask how I can play with nails.
