Need to get out of my head

I struggle having an orgasm. I have a problem where I am so focused on making my husband happy and wanting him to finish that I can’t really enjoy it myself. Even when he tells me he wants me to finish, then I get even more in my head and worry that if I don’t finish that he will feel a certain way. I am also very quiet, I want to be able to express myself during sex but I feel silly when I do. Ugh. Help.

Any thoughts of things I can do to help me get over this? There are times where I do finish, but it is few and far between.
