I agree with Julie. Fantacy playing, roll playing, maybe make a date to meet a "stranger" in a singles bar. (Of course, you will be the stranger, and he will be the one meeting you)
There is so much to do together that can help with your sexual urges and needs. Do some research. Is there anything that you both haven't tried yet? Since we have been in the lifestyle, we have expanded our own sexuality in the bedroom. Swinging is like the icing on the cake. If he is the reserve type, plan something that he may be hesitant about, but trusts you enough to try. Let us know how you are progressing.
