You don't necessarily have to participate, but going would be an interesting experience for you both. Sit and watch as you both touch yourselves to climax. Don't burden each other with expectations that would make year-olds nervous. Have sex in a restroom that could lead to discovery at any moment, so you'll have to be quick. Go to a strip club together. Have sex in a fitting room.
Make note of your favorites so you can use them again in the future.
Plan A Sexual Weekend Getaway
It's easy to do. Take your partner with you to the sex toy shop. Put them on a list and then start checking them off! Make sure you do this one late at night so you don't risk any kids or adults walking in on your fun. A really big dinner makes sex less likely.
