I went 7 days without sex on a family vacation, and woke up humping the air in tha hotel room bed next to my mother. Not joking. And it seems like the more I have it, the more I need it. I have no desire to live without sex, and I dont think I could live without masturbation at all. I'm female, by the way. I believe sex is empowering and healthy, though my desires can get pretty filthy and degrading if I go too Long without release.
And, "ugly", I feel bad calling you that because you seem like such a devoted and caring person, there has to be some way to work things out with your husband. Would he be open to watching you with another partner in a sexy show that you're putting on for HIM? This way, you're getting release while making your husband feel involved. I'm not sure if you're open to this, but would you take a female partner? There is certain, er, equipment a woman can wear to give you the same intense physical sensation of sex, and this may be less objectionable to your husband. Men tend to be less jealous towards females than other males. You say one night encounters feel hollow. You have the option to take a steady lover, who you could meet on a regular basis. Involve your husband in this relationship, allow him to watch and participate in whatever way he can. These suggestions may seem a little taboo if you or your husband have old school values, but it hope they help. Best of luck!
