whoa - too scary for me!!! i have a hard enough time handling one relationship - and have not done that great a job at that for years. mixing it up with more than one just sounds like trouble to me. the casual sex sort of thing reminds me too much of abuse. almost inevitable that emotions will get involved sooner or later on somebody's part. and then - lots of hurts...

seems like you might be better off getting yourself strong and healthy and stable first before making any huge changes like that.

...my opinion,
"Tell your heart that the fear of suffering is worse than the suffering itself... And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity." - Paulo Coelho
