I've been in that boat before and it sucks. I've brought up multiple partners but hubby thinks it's a fantasy and not that I feel an insane desire that he can't satisfy (only because he has to work, sleep, eat, shower, ya know) For a time I had a job as a phone sex operator (no joke) and OMG did that help. It took the masturbation to the next level without me actually crossing the boundary. Have you tried one of the live links or lava line kind of things? It's free for women and it might keep you from crossing the line until it 'calms' down.
