husband not good in bed

I need some advice my husband isn't very good in bed. we've both only ever been with each other but he just doesn't listen to me. I have straight up told him things I don't like but he continues to do it. I make sure I moan more when he does something I like and give cues when he does things I don't like. I tell him things I want to try but he never does them. it's frustrating because I'm never horny because it's not that fun for me and I don't get off as much as I would like but he just doesn't listen. ....... edit for comment**** yes we had sex before we got married but we got married at 18 and now we're 25. when we were 18 I didn't really know much or any different lol
