Master had me fill one out at the beginning of our relationship - it was a great way for him to see what I would and just plain wouldnt do.
After a while he also filled it in too so we could see if we were compatable, luckily yes we very much are - also it gave me a bit of an insight into what games and fun I should expect in the future based upon what he also wants to try.
The downside was I ticked the wrong box on one thing and even although I told him later when it came up in discussion he wont let it lie and says he has evidence that I am up for that particular kink - which I'm not, but the more he goes on about it............
