For everything between two lovers , you have to remember that your partner cannot read your toughts and have an image of your desires and fantasies if you don't tell them .
Make a soft approach of your desire or fantasy , tell him (partner) that you are interested by some different fantasy , you are like you are , and if she love you she love you for what and how you are . Living with her during many years , and never talk about will be stupid , talk and share the specificities of your life .
But let her the time to agree , to be confident , to learn to be your partner with the special fantasies , at the same time be very interested and open to her fantasies , if you have , may be she too , so nice for you to be in her fantasy . It is also possible you have to awake her fantasy , be patient and helpfull , you a bit blocked to talk about your most private life , she too .
Open the doors slowly , discretely don't slam the doors open .
