Where I'm at on guys... advice appreciated

So. Guys.
I've been thinking a lot lately about the amount of seriousness I really put on my relationships with guys. And I'm thinking that I'm way too serious about it. I think it may be because I've been so hurt before, and I just don't want anyone's feelings to get hurt or bruised or damaged, mine or the guy's. I think about things like that way too much, and I want to be better at just having fun with someone, and not getting so wrapped up in the future of it all, or where it's all headed, or whether I'm making a mistake or not. Proverbs 4:23 says, "Above all else, guard your heart for it is the wellspring of life." But how heavily guarded am I? Is it a bad level of security, to where I am so closed off no one could ever get behind the wall, unless they are perfect in every way? Or is it a good level of security, where the guy needs to be perfect, because anything else would be settling?

I want my next relationship to be able to move toward marriage, if it lasts that long and gets that serious, but I don't want to be closed off to whatever is right in front of me because the person isn't perfect. I want to know the guy well enough as a friend to where I can trust him to be a good boyfriend, and I want to like him in that way before I say yes to dating him. But that isn't the way it always works for everyone. Why can't I just say yes to a date without any fear of the future or whether I like him or not, or whether he's a good friend or not? (IMPORTANT POINT: nothing has come up like this at all... just a wonderment.) I've only kissed one guy, only said "I love you" to one guy, only been in one relationship, only been in a long term relationship (2 years), and it was amazing. But in the end, he didn't even like me that much anymore. It wasn't fun anymore. It didn't neccessarily start off in a really daring and fun way either. It was good... don't get me wrong, and he was and still is an amazing guy, but he wasn't right for me.

I need someone who will bring out the outgoing, fun, bright side of me, and at the same time, be there to be mellow, comforting, compassionate, and serious when he needs to be. I want a best friend in the guy, who will know me and love me for who I am; someone I won't be afraid to tell my secrets to, because I can trust his secrecy. I want someone who challenges me spiritually and not physically; someone who won't push the limits, but will be honorable and admirable. And most of all, I want someone who will always love God more than he loves me. Otherwise, it won't work. And he needs to be someone who wants the same from me. Here's some more list items:
~can take a joke and laugh at it
~can handle sarcasm, and puts it out there, too
~would go to the mission field if God told him to
~is totally fine with just laying around in sweats and socks all day
~will take care of me when I'm sick
~will bring me my favorite flowers, just for the heck of it
~can put up with my goofiness, utterly annoying forgetfulness, and my lack of cleanliness
~is willing to be there, no matter what or where or when.
~quick to forgive, and slow to anger
~loves cellulite :o)
~gives great hugs
~has a killer smile
~will watch a chick flick every now and then
~doesn't make me do things I know I won't like
~is fine just holding hands, walking in a park, and being with me.... even if that's the whole date
~likes to go dancing
~loves surprises
~does sappy romantic things spontaneously

These are just a few things that I would love in a guy, but not all of them have to be there for me to love him. I am flexible on most of those things. And I guess I'm just doing this because I am just really wanting a boyfriend, or just a guy to be able to call at 1 am to talk with or get a hug from. But it's a real desire of my heart. I want someone to miss me when I go away, or someone to want to come with me. And I don't want to end up in an empty apartment in 15 years with two dogs, hoping someone will call or come over just so I can be less lonely.

I just figured I should see if there's something wrong with me before I go blaming the world.
Am I not putting myself out there enough? I admit, I've only met one guy at school so far, and now he's a good friend of mine, but it's been a few months, and he's the only one. Should I be flirting more, searching more, doing whatever girls do? OR should I stay as I am, waiting on the guys to do it first?
