You can work on this as a couple. Sometimes this feeling of not being attracted is not personal but it is the change that comes in a relationship when it moves from passionate to comfortable. It takes work to find that passion again. You can try to do this on your own. Make quality time for the relationship. Go on date nights. Try to make time special. Bring in romance - candlelight dinners. Self educate yourself on bringing back the romance. Get him in on this process. If it turns out you can't do it on your own then see a marriage counselor. Relationships change and this can require professional help.
You have to engage your husband into their process. Try things you find and make couple time your first priority. You are young and you can try sexual positions or aids to have better sex. AIf he is motivated this can change. If not then that is a bigger problem
