Ak33, if it helps, have a look at the first 2 paragraphs of Lesson T5.
There's also the first part of T39: "In yoga, ejaculation is mostly foe, but we are not fanatical about it in the lessons. Occasional ejaculation is not a serious barrier to yoga. Frequent ejaculation is. This is not a moral judgment. It is just a fact of prana/energy management."
The tantric elements go together alongside the main sitting practices, and those take time to unfold.
Probably a lot depends on the person. On this end, brahmacharya has been a bad struggle since I kept testing and exceeding its limits, with resulting pain, exhaustion, loss of proper sleep, and if making use of the extra energy excessively even depletion to the point of depressive symptoms. On a medical test, one main hormone did indeed score above the normal range, so there's no saying it's psychosomatic. The perseverance has been paying off, and things are not nearly so bad, but with constant management and oversight. Age does makes a difference too, so things do get better with time. I also think the sitting practices have an immediate balancing effect, since much of the difficulty with brahmacharya & tantra was prior to finding AYP.
There was a saying from another system that really appealed to me. It basically said the quantity of jing (dense form of prana and sex hormones) we are born with is always more than enough to serve towards a higher purpose, and so it does not matter whether we have little or a lot as long as we protect what is available.
So it seems like you're doing just fine. Ease back or press forward as necessary.
