Fantasies

Im not the type of person who really has fantasies or anything like that. For me it's a case of if someone tells me something or asks if I would be interested then it gets my attention especially if it's out there or if I never heard of it before. It's not that I'm unimaginative (or maybe I am), it's more that I just like to go with the flow. For instance a close friend just asked me recently if i would flog/whip her until she reached sub space something she had always fantasized about doing(all those who are into Domination and submission will prob know what I am talking about). That is something I never thought about, researched or even knew something like that even existed. So I asked her about it and she explained it all to me. I decided to give it a go, more for her than for me and while it will never be my cup of tea, the experience was something new and exciting.So just wondered what fantasies people have, outrageous, fulfilled or unfulfilled and if unfulfilled then why so i.e can't find the person/s, not game etc.
