Abstinence makes the heart grow fonder. While you've had longer stretches without stretching your sex muscles, the circumstances around this break make it harder. Like most of us, you probably use sex and sexuality to express or represent many things for yourself. In other words, maybe beneath your rash of hornies is also shades of fear, anger, guilt and anxiety.
Does that mean your lust is false? NO, not at all. You're dating this guy and presumably find him sexy. In addition, you likely had sex with him on a regular basis leading up to his departure so your lack of current ass is sort of the shock of going cold turkey; it takes a while to remind the body "sorry, no bone for you tonight, Sweety." (See my earlier article on booty begetting more booty.)
To answer your question, there isn't a way to make "it" stop, but I wonder, do you truly want it to stop or just be tempered? Next time you're in heat, slow down the horny feelings and see if it is laced with those other themes I had mentioned (fear, anger, guilt , anxiety, and more.) Once you figure out that your horniess might be a catch-all for other feelings, you can then isolate its parts and explore them.
From there, masturbate when you can actually distill hornienss and keep a diary, speak to friends, family or a counselor for the other stuff. Remember: a vibrator makes a great masseuse, but a terrible therapist.

Also- when you're single, there is always that chance you might get lucky! Hence, you don't feel quite as frustrated.
Presuming you plan on remaining faithful while he's gone, you've guaranteed yourself no sex until he's back... very frustrating.
Invest in a good vibrator. And good luck.
In all my years I never recognized this so obvious truth that you so casually mentioned:
"You probably use sex and sexuality to express or represent many things for yourself. In other words, maybe beneath your rash of hornies is also shades of fear, anger, guilt and anxiety."
OMG! But you are right on, Amit. Even if what is beneath the hornies is not so negative. For example, it may be a zaniness, creativity, or even dominance that is suppressed and only unleashed in bed. But there is often something else there either way, that is so true. Sheesh, what an epiphany - Thank you!
