Wow, I've actually done everything besides the Sybian (Riding doesn't do much for me anyway) and the lake/ocean (and that sounds like BV waiting to happen).
I think my list is more like:
1) Sex machine
2) Glory Hole
3) CNC
4) Ball gag
5) Trampoline (I've had lots of people tell me it's dangerous and an injury waiting to happen, but life is short and I'm horny 😂)
