And of course I have to add my own two cents. I enjoy a good mature scene, but unless there is plot behind it, thoughts, and some history, it tends to be boring, quick, and my character running to the door. So there is this chick and she writes this intense line with my guy and decides to never back their 'assumed' friendship up with real play. No, no...she is going to IM me with "She needs to get laid, lets play."
Riiiiiggghtttt.
If she calls my char her bed buddie one more time or expect him to understand and feel for her char because they have 'assumed' a friendship, she is out of her bleeding mind. I cannot and will not write a friendship line if all you want to do is cyber.
