What did he really mean when he said that?

My bf and I have been together for over 5 months now and we both love each other. I haven't had sexual intercourse with him but we have done almost everything else. However, he has never given me oral and has never been able to give me an orgasm. I told him that the fact that he can't give me an orgasm is bothering me and he says he is trying. Yesterday, we were in bed and I was giving him oral and he was rubbing my clit with him fingers. And at the it made me smile to see he was trying. He asked me why I smiled and I said "nothing... I'm just smiling." Then he kind of broke down and was like "I feel like I am a big disappointment." Then I was like "Nooooo, don't say that.. you are doing good and blah blah." He said he doesn't know what to do. And I asked him if he has ever seen a man please a girl in porn and he said he always skips that part. I had nothing to say. Then he was on a call for like 30 mins and came back and said he was sorry. I was like "You do know that you can't please a girl only by using your fingers." He said "yea I know." And I asked him why he never did that before and he said he doesn't know. He said he is ok with giving oral and that he just wants to know exactly what to do and that is why he never did it before. I can't understand if he is lying or telling the truth. Why do you think he never did that before?? I am a very clean person and I always keep clean.
