If you don't see it (a 3rd person) ever happening, then a toy will have to do...
It's not the same. But it is still a pretty awesome sexual experience, one I think every woman should have in her life.
The difference between a man and a toy vs. two men?
Well, first, it is lacking the physical and emotional thrill of having another person in bed. That can not be understated. As a woman, pinned between two men thrusting into ME, who's entire focus is ME... well, it's quite a sexual thrill. (And flattering too). There is much more complicate foreplay leading up to the actual event, which makes the whole thing more intense.
Let's talk about intensity.
I have often fainted from the overwhelming intensity of a DP orgasm.
I mean my eyes roll back into my head, my body goes completely limp, I start drooling in a most un-ladylike manner, and remain almost completely unresponsive for up to a minute after my orgasm ends, (which can take QUITE a while, thank you). I stay sort of fuzzy and confused for several minutes afterward, much more so than after my usual orgasms.
I have learned to warn my partners of this, as men tend to totally panic when they think they've killed me while fucking me.
I also usually have multiple orgasm from this, so long as my partners are able to continue, with each orgasm building on the previous, which leaves me a quivering mass of flesh for a while after.
The whole experience usually leaves me a physical and mental wreck for several days afterwards, and usually I am very, very sore. Not just vaginally and analy (yes it hurts, but ohh yesss it IS SOOO worth it), but every muscle in my body screams like I spent the entire day competing in a triathalon. (I tried a mini triath here last summer, so I know).
I have done this with:
1) Two men (best)- I pretty much always have the response above.
2) With a couple, man and a woman, while she wears a strap -on. This is almost as physically intense and is in someways better, because it lasts a long time. With this combination, I sometimes faint sometimes not, it depends a lot on the skill of the woman wearing the strap on, and YES there is skill involved in fucking someone with a strap on. My beloved Leigh is VERY good at it, and when I am between her and a man I always have the most extreme orgasm.
By the way, with a woman wearing a strap on, it usually works best if she enters me vaginally and the "real cock" enters me anally. Better control, less pain and risk of injury.
3. Two women wearing strap ons. Always fun and intense, but I rarely faint. But lots more happens and it lasts for hours, so don't abandon this idea. But there is risk of injury.
4. A woman with a strap-on and a toy. (see above). Lots and lots of skill involved.
5. A male and a toy. Fun, sexually intense, and still results in a spectacular orgasm, but almost never the "fainting" level. But close.
Frankly my best orgasms from #5 come from closing my eyes and imagining I am sandwiched between two men.
That's all for now. I hope this helps.
(What can I say, I am a very self absorbed woman. Sexually, I crave being the center of attention)
