Need new “phase”

Hello my husband and I been together for 11 years and my husband loves sex. We call our ideas “phases” , he loves to go to swinger clubs, go outside half naked and be naked in the car. Sometimes he dares me to walk outside naked to throw something out in the garbage. And we also have tried bdsm, threesomes, dildos, sex machines etc. My point is these were all his ideas since he is into sex more than me now is my idea to create something or a new “phase” anybody with a really dirty mind and help me find something? It would be greatly appreciated, something that we can do in the house and hopefully he likes it. No anal play he doesn’t like it.
