me, my boyfriend, it and the L word. PLEASE HELP

Ok I got an issue and need help on what to do and say. He is the perfect guy but I have some trust issues and self confidence issues with doing and saying things. We talk about everything just keep that in mind. We were talking the other night about a couple of things but he told me he was really worried about something. So I asked him what it was and he told me he was embarrassed that when we were making out or I was kissing on him or something that “it” was in the way and that he thought it was a turn off to me. I told him it was a turn on to me because it made me feel like I was doing something right to get him so turn on. But he said it was embarrassing to him because he was all ways having to fix his pants and that he does not use it for anything so its in the way. But in the same sentence he told me not to think that he was hinting at something because he knows I am not ready for any of that. Not that I have a problem touching “it” that’s not it. I don’t know what to say to him he feels self conchies about it. He not only worries when he gets turned on but he feels like he is not up to size either. But he keeps telling me not to worry about but I know it bothers him. He all so tells me that he is not going to let me do anything tell he thinks I am ready for that type of things and I am not ready. What do I do or say to make him feel better about it I feel like its my fault. Ok now my issue with him I have a hard time with the L word and saying it. I have feelings for him but I don’t know what they mean. I asked him how he felt about the L word and he said he did love me and when I asked him how come he did not say it. He told me that he knew I was not ready to say it and when I was he will say it back. He told me not to worry about it but I do because I know how he feels. But I don’t understand how to sort my feelings and what L* feels like. How do you know when you are ready to say this. God please help me I am so lost and confused.
