Sex advice

So my husband and I have been married 5 years. And he’s a lot more experienced than me in bed. He’s not my first but I used to be pretty insecure, like keeping my top on while having sex because I was insecure about my small breast size. I’ve gotten better like I can have sex fully naked and have fun he’s the only one that I’ve been able to orgasm with. Our sex life isn’t boring, we try different positions, toys, exc all the time. But sometimes I still catch myself being insecure. Like not wanting to make direct eye contact with him or my mind wandering like “I wonder what he’s thinking” things like that. Which doesn’t happen all the time, but it’s still lingering in our sex life, and prevents me from “really getting into it” sometimes. Like I struggle to tell him what I really want because I’m embarrassed I guess lol. Like the other day he was giving me oral and I really wanted him to give more pressure but I wouldn’t tell him, because I didn’t think it would sound sexy, or thought it would break the mood. I basically need advice on how to break this habit.
