I did mine a while back to place on a certain fetish site that I'm sure many are aware of, and I thought the process of thinking seriously about what I actually enjoy versus what I think I should enjoy was informative. Seeing other people's results that are broadly similar or vastly different is very useful. It could save a shed load of hassle if we showed all potential partners our list of turn-ons and turn-offs. Of course, it's great to ''discover', but saves so much time to understand more from the off.
