Well... sometimes reality bites. LOL.
I do a fair amount of experimentation with hubby, but one of the first things I learned is that the transition from fantasy to reality is best done slowly. Baby steps. Lots and lots of little baby steps. Because while sometime might seem great in your head, if you plunge right in you can get burned (sometimes literally, although fire-play has never appealed to me... my Ben-Gay experiment was enough to convince me not to rush ahead just because one thing feels good 5 seconds in).
The next thing I learned was that, sometimes I love the fantasy and hate the reality, no matter how slowly I take it. I'm not surprised that many women who try out spanking and kind of horrified the first time they actually try it out in real life - it freaking hurts. And if your partner doesn't know what they're doing and take the time to warm up your skin, it can hurt even more. And not in that erotic "good" way that I write about. Although I do get wet from being spanked, I've discovered that it's more about what's going on in my head than how it actually feels - although I do like the pain a little bit.
A hardcore masochist, I am not.
I love to read / write about it though. I have an utter fascination with it when it comes to stories, but show me a video with real people or try it on me and I freak out. So not sexy. I can't watch BDSM porn most of the time because when I see the extreme stuff I'm like AAAAAAHHH. But then give me a few weeks and I'm writing about it and it's all sexy in my head. Brutal nipple clamps, fisting, caning... oh yeah, I'm all about it as long as I'm just writing. But if I see a porn picture of it or something I'm sitting in front of my computer cradling my breasts thinking ow ow ow and completely turned off.
Another example... I think it's pretty clear that I love writing in the non-con category. I have no real explanation for this, because I don't even like rape-play. A lot of women enjoy role playing it, but I'm not one of them. I completely freak out if it gets even close to that. I love being tied up or held down, but only if we're not role-playing anything... try to role play that and suddenly the ropes are claustrophobic and I'm panicking and trying to kick free. And it's not sexy.
So my major advice for anyone who wants to try to turn their fantasies into reality... take it slow. If I'd gone for a hardcore spanking the first time I'd tried it out, I probably never would have attempted it again... but now I can take more than I could when I first started trying it and enjoy myself. Don't worry if you don't actually like the reality, that's perfectly normal. It's still possible to seriously enjoy the fantasy =D And sometimes I go back and try things that I didn't like the first time round, just to see if my tastes have change.
I have to admit... I've used the Ben-Gay again since my first experiment. Sometimes I just want to feel the burn. But I still have yet to try out figging.
