i definnily don't think they ciuman in awakening atau the struggle because ive read those buku and also they don't kissin fury atau dark reunion so ill have to wait til i read night fall and also shadow souls. to see what happens between damon and elana.
i think that they had kissed in the fury( 3rd book) when Elena wakes as vampire and think that she's in cinta with Damon, they'd also kissed in the Nightfall (5th book) when she's healing him from malach, and in Shadow Souls they are ciuman almost all the time, hope I helped :)
I've read the descriptions of the books, anda know the bit on the back of them that only gives a little bit away? No idea what it's called. Well, Damon and Elena NEVER actually get together, not according to the texts. But they ciuman in the The Vampire Diaries; The Return: Nightfall plus. I don't think they do anything in the last one, need to wait and see when it comes out! Can't wait!!
