I think I would go crazy in heaven. Talk about boring. Sin is relative. In some religions everything is a sin. Being human is a sin. WTF? If a higher being created these amazing bodies for us, then why would sex be a sin? I just don't get it. Can you have sex in heaven? I mean, what are you supposed to do up there for eternity? Seriously. I'll take reincarnation any day or even just non-existence over an eternity of wallowing in perfect love or whatever is supposed to happen in heaven. I think, if there is a heaven, you make your own.
