Hi Nas,
Keep hoping, Nas, and keep trying some safe alternatives, until you get some relief. We have no choice but to accept this challenge that we have, and that others don't have. But, hey, everyone has it sown challenges in this human life.
I would like to know what is your usual frequency, in term of ejaculations per week, or per months?
I ask this, because, even with my pre-pack, I wouldn't control all of my symptoms, If I was to ejaculate more than once a week, and less is better still. For me, like for most POIS sufferers, the metabolic events that occurs in POIS seesm to be cumulative, and symtpoms worsen with higher frequency.
I suggest you work on your perception about libido and need for sex, in order to lower it as much as possible. Once a week, and once every 2 weeks, are good goals for a starter. After 40 years, I have become very good at that, and have done a huge reprogramming about the cultural aspect of sexuality, because it is not only our hormones that can make su frustrated if we abstain from sex, in my personal experience. The cultural identity of what is a "true male" greatly contribute to the frustration and urge to have regular ejaculations. Our instincts are programmed to motivate us to reproduce, but the cultural overlay can greatly strengthen our reproductive instinct - we are, litteraly, programmed by modern culture about how often we should have sex in order to be "normal". Also, publicity and popular culture ( movies, TV, magazines,..) are abusing the call to reproductive instinct in order to sell and promote about anything, and this can be made conscious and worked on. Moreover, some modern psychological science will say that sexual restraint is bad for the mental, emotional and physical health...hehehe...but for me, it has been highly positive! Too much of anyhting is no good, and the NoFap movement,, and all those porn addiction problems, tend to prove that our culture si over-sexualized, even when POIS is not in the picture..
NE will still be a concern, but regular masturbation at frequencies considered "normal" by current culture are not appropriate in our case, according to me.
Do you feel clearly better if you did not have an ejaculation in the last 10 days or so? If nothing else work, than abstinence, at least, should help. And, also, as Meshal have pointed out, such an abstinence period is needed if you want to test a new control method - otherwise, you are not in a "out-of-POIS" state to begin the test, and this affect the validity of your experiment.
