A few weeks ago I wrote why I ship Dean/Castiel. I would like to just add this (it will also be found at the end of the post linked as well)

I've been reading A LOT of others' metas on Supernatural and especially on Destiel. Because of this, I have changed my mind. All the readings of Destiel and how much they are in love has caused me to really want Dean and Castiel to kiss.

I know exactly how I want it to go down too. I want Cas to get severely hurt (even though it'll cause my poor heart to weep) and he's "dying". Dean doesn't know if he's going to make it plus he needs to keep him awake. In order to try and wake him, he kisses Cas on the lips. Afterwards, when Cas is all better, of course, he denies the whole thing and he has to sort through his emotions and once he does figure out he loves the guy, wonder if Cas loves him back.

After that, I'm not sure what I want to happen to get Dean to realize Cas loves him as well, but either way, eventually, they'll end up together and both of them will then kiss each other in a non-life-threatening situation.
