bad idea. i mean, i suppose its a GOOD idea, but they dont work out very well. my last relationship started off like this, and its definatly not worked out quite as planned. fun for a while, but people grow on you, and the first time somethin happens between the other and someone else shit hits the fan. if its a monogomous, but just-sex relationship, thats fine, and actually alot of fun, and it keeps things fairly uncomplicated. so my vote, if its just people hookin up on a reg basis, but not without hittin up other people, things can get bad. but if its just two people hangin out and fuckin, its usually all good.
