How do I keep my curly hair looking wet for the whole day without using gel or mousse?

I am a male with very long very curly hair (like Sayid from LOST). I love having it this long and in the morning after I shower and while it is still wet, it looks great but as the day progresses and it dries it goes everywhere. I use to use gels and mousse to keep it looking wet; however, all the gelled hair that behind my neck area gets cracked from normal movement so I have two phases of hair that looks terrible. Slick curls on the top and a fro in the back (almost looks Mullet-esque). What product can I put in my hair to keeps my curls? Someone suggested something called "serum," would that would? What do you guys recommend? Like I said, I'm a guy so I don't know much about these products nor do I own a blow drier but I am willing to buy one if needed because someone also suggested using the serum and a blow drier with a "diffuser" attached. Please Help Me Out!!!
