When it is gone, you will want it back so much more than you want to get rid of it now. It is much harder to get lust back than it is to get rid of it. My advice is that you never let it go, and that you embrace it and love it. It is the life force, itself. It is the source of creativity. It compells you to try to create children. It compells you to feel love. It is a magical, necessary thing.
But you want to make it stop. I assume there are a number of hormones you could take to suppress your estrogen and testosterone levels. That should make it go away. You could get fat. I think that would reduce it. You could get depressed. I suspect that if you did a bunch of drugs or drank a lot of alcohol on a regular basis, you would diminish it. Marijuana might increase it, or it might decrease it. Anxiety would make it go away. You could fail at any number of things.
As you can see—things associated with reduced lust are not good things. Personally, I don’t think it’s something you should mess with. It’s the life force and the creative force. You don’t want it now because it reminds you of your relationship woes.
Tough it out. Lust is an excellent thing. Keep it alive. It will bring men to you. They can see the glow of a woman who is lusty. It’s an aura you give off. If you really want to be in a relationship, then cultivate your lust as much as you can. Masturbate often. Let men know you are alive. They will cluster around you and when you find the right one, the sparks will fly and you can indulge your lust and so much more that is good will happen for you.
