Hubby super self conscious

My husband has a smaller than average sized penis. I love it and everything about it, there are a few positions we’re not able to do, but our sex life is still very fulfilling. He’s amazing (I mean earth shattering, legs shaking, can’t walk afterward amazing) at oral. I’ve been with guys who think a big one is all they need to get me off, and I would choose him over any of them. He knows just what to do with it and is the only man to ever make me orgasm from penetration. I know he’s self conscious about his size and I feel like I tell him all the time how good he is in bed and at everything he does, but he’s still self conscious. The other night we were watching a tv show and they mentioned doing a penis enlargement. He immediately got on his phone and started checking out pricing! I don’t want to hurt his feelings or say that they’re not valid, but that’s so extreme. I told him I love his body and everything about it and I hope he never feels that he has to change it for ME, but I’ll support him in whatever he thinks is going to give him confidence. Idk ladies, what else can I do to convince him he’s perfect the way he is?
