Can be very real. I think the internet provides an unrivalled opportunity to find someone that you are comfortable and compatible with.. the "just right" one. If the physical attraction is there through real pix, it can definitely happen.
Impossible. its an over rated lame game.
You can't kid yourself forever.
depends if the person is who they say they are
Speaking from experience both. I was told that it wasn't real.. Maybe in some ways but if you get emotionally involved..it's real, VERY real.
