What is going on with me, my boyfriend is doesnt turn me on!?

Hi people, me and my boyfriend have been together for a bit more than a month; its not a long time I know. The problem is that he doesnt turn me on enough so he can penetrate me. I’m a virgin by the way, not because I haven’t had the chance to have sex, but because I chose it. I had quite a few boyfriends in the past and I have done things before, but not sex, cause I wasn’t feeling ready with anyone of them therefore I decided to wait. Now that I met this guy the feeling is different, he cares about me and he shows it, and I care about him as well; I like him a lot and I miss him when he’s not with me. I’m feeling like I wanna do it with him, we tried plenty of times but its not possible. I’m too tense, and its a bit too painful! He understands me and he is patient, even though he wants to have sex. But I noticed that with him I’m not wet enough when we’re making out, whereas the guy I was with before him, he was turning me on in no time even though I didnt want to do it back then. I don’t even know the reason why he’s not turning me on, cause I like him and he’s actually the first one that I feel I want to have sex with. We tried plenty of times but its just not happening. As I said before he’s patient and he’s not pushing me to have sex, but the last few days I think he’s trying to avoid me because we’re not having sex. I understand him in a way, cause he tried a lot of times to help me relax and enjoy it but I just can’t, so I think that he’s kind of fed up with it. He was supposed to stay over last night and he left after we made out without having sex, and today we were supposed to meet up and he cancelled it. Im feeling bad everytime that we’re trying to do it and I can’t because I want to please him.
