Maybe sharing your fantasasy to him is a good idea. But most of the time, men have different fantasy with girls.

Just read your question again. The part about "...wild yet disturbing fantasies" just stuck out at me. Once again I say share. Particularly if he's aware you find them disturbing and spurring you into sharing. If you can't share with your partner who can you share with? It may very well put it into a perspective that make you more comfortable with your thoughts. One other suggestion might be if you feel TOO vulnerable sharing it with him you could always enter it as a topic for others to comment on - even if you just do it with a different screen name. You shouldn't have to keep disturbing thoughts burried away in your head. Once again, you might find the thoughts more rationalized hearing from others. You might be surprised from what you hear(especially from this bunch-LOL).

Yes, definitely share. I can't immagine any X-rated fantasy that would freak me out-except in a positive way. That is of course that I knew the lady quite well beforehand. Well, now that I'm thnking of it I suppose there could be some-(no animals,children,fecal matter,or S&M/Bondage). OK, the animal thing --so long as it was just a fleeting fantasy and not an obsessive desire. Oh, alright, the S&M thing too---But, if they were really into it, I'd have second thoughts. ON the other hand, your partner should feel open about expressing his fantasy's also. And that should be part of the exercise, but ,.... don't be surprised! Hopefully you both know eachother quite well before you start sharing such intimate information. Going on a first or second date and having the woman tell me about a fantasy of being done by a large horse(as compared to a small horse?) would probably give me second thoughts. One other thing- exchange fantasy's one at a time over a long period of time. Hearing about the horse, the virgin young boy, the whips,and the double ended dildo all on the same night might be a bit much.

go and tell him that you want to experience whatever it is and see what happens its not like you going to die

I bet your boyfriend has some pretty wild fantasies of his own. Why not share? And if you feel like starting things out slowly, make up a new one that's more main stream to get him started. After you warm him up, bring on the full heat. I bet he can take it! Enjoy!

Your fantasies are part of what make you, you. I'm for 100% openness so I would suggest disclosing your thoughts and fantasies and see what he thinks. He may propose on the spot or back his bags. Why not find out sooner than later?

Obviously, it's more complicated than that, but for the long term, why not see if he's into what you are? I can tell you from my perspective as a guy, I would absolutely love hearing x-rated fantasies from my girlfriend.

I think it's good to have some thoughts that are just yours. It's kind of a privacy thing. Sharing it may take away from it. You could still tell him some of your fantasies or what they're about, but consider if it will it bother you if he likes them? if he wants to act any of them out? Are you worried any of them would make him jealous?

I think it would probably be better to talk in more general terms about how you both feel about various practices. And ask him about his fantasies, if you haven't already. The bottom line is I don't think you have to tell him anything, but if he pushes too much, remember that he can never check what you tell him on this one thing.
