Am I being unreasonable in my hurt feelings?

Am I being unreasonable in feeling hurt? This guy I've been seeing (he won't call me his "girlfriend" for whatever reason, even though we've been together for over three months) recently revealed that he won't ever go down on me because he thinks it's gross. Obviously that alone is disappointing, but what's worse is that I've gone down on him several times (each time after he practically begged me to), and I finally did anal with him despite not initially wanting to. I feel a little manipulated now and hurt, especially since he said before that he'd go down on me at some point if I wanted it (I've made it very clear that I do). And of course, the fact that he finds it gross just makes me feel even worse, and it's starting to make me see him as rather immature (he's almost 27).

Then yesterday he said he'd take me out for lunch after I got out of a meeting, but when I texted him and said I was out, he called me and told me he was instead going to lunch with his friend. I wasn't mad at first, but then all of a sudden all these feelings of hurt started rising up, and now I don't know what to do. I really wanted to talk to him about all of this last night, but he was already out drinking with his coworkers by the time I got out of work and I just didn't have the energy. Trouble is, I don't have much relationship experience and don't even know how to begin bringing up my hurt feelings with him.

Am I being unreasonable? And if not, what should I do?
