If this sounds like what you are experiencing, I do believe there are ways in which to get your husband to view you more sexually. It will be a process, and may not always move perfectly forward. It sounds like you have tried talking to him. So, next, it may be time to just act. I recommend trying something small first. Start with some lingerie that is outside of the norm of what you may typically wear, but that aligns with what type of sex you want to be having. Maybe wear something and put on a little show for him, like dancing or a strip teasing for him.
Perhaps you initiate sex one night. Try to incorporate some small-ish acts into sex that you aren’t normally allowed. Try a different position. Masturbate in front of him and tell him he isn’t allowed to touch you until you say so.
During sex, see if a situation doesn’t present itself where you can intervene. Again, I recommend treading lightly since he has been so resistant. As each little circumstance comes along, you can build on each of them towards bigger changes. The slow and small progression will give you little victories to celebrate while slowly testing his limits without totally freaking him out. You definitely want to be mindful. If he does catch on, just stick to asking if he likes what you are doing. If he does, keep going. If not, lay off for now. Don’t get discouraged if you have to back off a little. Just try something different next time and gauge his response as you progress. Good luck!
