Thanks for your advice guys. I think I will make the pro/con list because it is something I usually do when I'm confused.
I'm not looking for an one-on-one relationship. Due to school, I really do not have the time to invest in one. However, I like having someone I can dial-up when the urge strikes me. And not to mention the sex is great between us.
Futhermore, most people can not handle a friend with benefits relationship because one of the two partners will stray from the rules....

however it was never a problem for us.....
