Am I bi-curious. I like shemale porn, and I like to use toys in my ass. I have often wondered what a real cock would feel like instead. I have no attraction to men at all. But I do have a MMF fantasy including my wife and I with another guy.What do I do?

Difficult because it depends on what your wife thinks of this. If she is interested, then you need to explore it with her and decide on another man. If she is not, then your best bet is to join another couple as the 3rd party.

Take the next step. Find yourself a "top t-girl".

tell that guy to insurt it in you and then tell us, how it feel.

You aren't bi-curious if you don't think guys are attractive. Tgirl curious IMO

It sure SOUNDS like you're "bi-curious" but you're certainly not alone ! I think a LOT of guys ( both married and unmarried guys ) become "bi-curious" at some point in their lives but some are reluctant to ADMIT it ! You sound a LOT like me - I don't have any "attraction to men at all" either - I have NEVER looked at a man and become aroused sexually ! In the fantasy my wife and I share of doing an orally bisexual threesome with another guy ( we even simulate it using her dildo ) I never even see a face - all I see is a cock as my wife and I share sucking it together ! I'm not especially interested in shemale porn or using toys in my ass but to each their own - right ? I am beyond "wondering what a real cock would feel like" in my mouth - I fantasize about it CONSTANTLY and would absolutely DO IT if I could get my wife receptive to at least WATCHING me if she wasn't willing to JOIN me in sucking a cock ! All you can really "do" is TALK to your wife about your curiousity and HOPE she's receptive to exploring it by fulfilling the MMF fantasy you have ! If she IS willing to fulfill the fantasy you're IN but even if she ISN'T willing to fulfill the fantasy that's better than not even having a CHANCE of fulfilling the fantasy with her ! Although the simulations my wife and I do using her dildo don't SATISFY my desires they do help to VENT them ( at least temporarily ) and it's a LOT better than her not even KNOWING about my curiousity and not even having the simulations of the fantasy ! Who knows - some women get INTO fucking guys in the ass with a strap-on ( my ex-wife really got into fucking me with a strap-on and although it was an uncomfortable experience for me she got SO turned on fucking me it turned ME on enough to do it whenever she WANTED to ! ) - YOUR wife might be ONE of them ! ( Some women get turned on to the idea of guy / guy sex too - the simulations turn my wife on a lot more than she THOUGHT they would ! )
