If you think you've already tried a lot of things and you are a little more adventurous than your prude friends, you might want to consider hiring a professional photographer to take some sexy photos of you.
There are really two ways you can go about this.
1. You have the photographer take pictures of only you.
2. You have the photographer take pictures of you and your spouse together.
I've actually done both, so I'll tell you about my experience and then let you decide if it's too much for you to try. I originally brought this up to my husband after watching a porno with him. I said it would be sexy to have someone take pictures of us while we have sex, and he agreed. We didn't talk more about it, but I sent out a couple emails to see if there were legitimate photographers who do things like that. I got some solid replies back and told my husband.
We looked his his portfolio together and agreed to meet with him to talk about what he had in mind. The photographer came over with all his gear and after we talked for about 15 minutes, he made us really comfortable with the idea and we began posing for him. He took pictures while we had sex, gave us some directions (move your hand, lift your leg, etc.), we paid him and he left his SD card with us. We sent him a few of the pictures and asked him to edit them for us, and he did.
This is one of them.
It was an experience we'll always remember and we got some really cool pictures out of it. It was exciting to be documented and watched like that. Fun to know someone was seeing us as beautiful art.
So my husband said he'd be into doing it again and he'd let me pose for something like that by myself, so I did. I called the same guy and he came back about half a year later to take pictures of me by myself. I gave the pictures to my husband for his birthday and we had amazing sex!
