Need some sex advice and courage in bed..

So saying it short, in all my previous relationships I liked domination and now as I have this wonderful guy- my husband, I just feel 'blocked'. He doesnt insist or anything and we have sex quite often. But I just feel weird with myself about this, I would like to bring this old me back as this man is so worth it, tried a few times but just couldn't get that moving I dont know like I was feeling not enough for him. Even when I give him a head I would think if hes Ok, if I should do something differently and it stops me from engaging fully , letting be wild without thinking. Its like im hiding my inner me from myself and worse I dont know if I could bring her back and Id love to.

What can I do guys?

EDIT: hes never made me feel that hes not into or im not enough or all i do sucks. Its rather me myself and I thing, hes not responsible for that. In fact, he knows exactly how to make me feel sexy or horny, and I never reject him in bed its just a block in my head to go deeper with what I know I could have.
