Seems to me that you are being a bit selfish here. Your Dom is going though a health issue right now. As a good sub and a friend you need to be more supportive and understanding of his situation. Right now he is healing and that is a physical and emotional process.

You do have needs, yes... but right now his health and recovery should be of greater concern to you than just your own gratification.

Don't mean to be harsh, but somtimes as a sub you get and sometimes you give. It goes both ways in a good relationship.

Be there for him and encourage him and let him know that your connection isn't just about the "needs" and you might find that you have a better relationship in the end.

And in the meantime, a good vibrator and lots of batteries might help you get through.
