Sexting?

I have just newly started seeing this guy, we have been talking for a while and went on a couple of really nice dates. We have kissed and it was great and I really do like him. 
We have been "sexting" quite a few times and I am just wondering if maybe it's too soon to be doing this? On one hand I am so attracted to him and want to be honest about that, have a little fun with it and get to know each other intimately but I'm also scared that he might just become attracted to me because of my sexual nature rather than for who I am.
Thoughts?
