Am I bad a gf?

I have been with my bf for like 3 years and we kinda live far from each other. So sometimes we’ll do sexual stuff on FaceTime but I’m like really shy. I also don’t feel comfortable in my body even he reassures me that he loves the way I am, I still hate it. Like before I couldn’t even show my boob while being on FaceTime and I have gotten better but like tonight we were doing this thing and he told me to get naked and I did. I was into it but like it was uncomfortable and he asked me to him my 😻 but I couldn’t. He kinda got upset and said that I got him horny and I stopped midway and that I always do this. He was like it’s not the first and it’s not gonna be the last. I tried to tell him that overtime, I’ll be more comfortable but my issue is watching myself like that. I don’t mind that he sees and we have sex, im really comfortable with him. Im just not comfortable seeing myself doing that and I feel like im disappointing him all the time
