First Day with a Boyfriend and Already Pissed Off

What is up with men? I have not heard from Victor since last night. He said he would call me in the evening and then I never heard from him. I sent him a text message and called but have not heard back yet. Why do they act this way? One day with a boyfriend and he has already pissed me off. He is usually good about calling me every day. He told me that he wanted to come over and make love to me last night. I told him no, because I was not ready to take it to that level yet. I wonder if he is pissed off and that is why he has not called me back. I don't even know if we are still together. I am frustrated.
