well, i think it's better to live together before marriage, or try to be like a married couple... at least, TRY to live in together... because, living in together or not are very different from each other...

many things you will only find out when you live together... what if you only find out after married and then regret... it's a bit too late...

as well as... sex... everyone is different... you probably love him or her but not his or her sex... dont tell me that it's not important, as long as you love each other... be realistic, it does make a big difference... and dont tell me SOME people can make it... yes, SOME, but not ALL...
