Being more confident in bed

I think my husband gets a bit discouraged because I will sext him and act naughty and talk like I'm into anything, which I am.. but in the moment while we're getting freaky I barely make a peep and I go in and out of focus so I literally never cum and it's been this way for so long. He makes me comfortable and I trust him and love him so it's not him, it's definitely me and I just want to open up and be the freak I know I can be! Dirty talk is a huge one like I've tried it a tiny bit but my voice isn't sexy in my opinion I have the voice box of a small child lol. Has anyone else been in this situation?
