When you put in your profile you want someone to share your life, you should probably mean it. I'm at the point where I would like to settle down with someone, but want to take my time getting to him. That does not mean I will wait forever though.
The ideal guy would be someone who adds to my life, and I add to his. Someone who I can lean on in the hard times and laugh with in the good. Sexual chemistry is a must, if a couple isn't having sex then they're not a couple, they are friends.
