Over doing this in some people who may have borderline or low testosterone may become more of a problem than just a "blip".

Increased prolactin secretion following masterbation is NOT a factor in the aetiology of gynecomastia.
Prolactin IS a causative factor of gynecomastia, when levels of prolactin are VERY high, something that happens when an individual has a prolactinoma (a prolactin secreting tumor of the pituitary)
As those who have prolactinomas often develop gynecomastia and with it lactation from the breast.

Not to mention the older we get the lower our testosterone becomes.

Testosterone does not significantly fall with age. It is SHBG (sex hormone binding globuin) and estradiol that increases with age, binding testosterone and blocking the actions of testosterone respectively.
So it is the bioavailable fraction of testosterone that often falls with age.
The aging male often develops gynecomastia due to increasing shbg and estradiol. The average 59 year old male has more estrogens circulating in his endocrine system than your average woman of the same age who is not on HRT.
So testosterone deficiency (hypogonadism) or more accurately, rather bioavailable testosterone deficency is a significant cause of gynecomastia.
10% of all gynecomastia sufferers are attributed to hypogonadism as laid out in the 1996 white paper entitled Gynnecomastia by endocrinologist Glen D Braunstein M.D. The latest white paper by Endocrinology of Gynaecomastia by Ismail and Barth 2002 concurs with these findings.
The ratio of androgens to estrogens is THE singular cause of gynecomastia.
Androgens and estrogens are NOT significantly impacted by the release of prolactin following masterbation.
AbNormal,
Alcohol is very toxic to the testes and is a known cause of hypogonadism. A very obvious symptom of this fact is brewers droop. Testosterone levels fall following consumption of alcohol, whereas estrogens increase thanks to the aromatizing effects of alcohol. Given that NO is required for erections and NO is derived in part from testosterone, the lack thereof results in a limp or weak erection.
Alcohol is bad news for your androgen to estrogen balance in the short term and in the long term damage maybe permanent, meaning permanently lowered testosterone levels which is often accompanied by.......... yes you've guessed it- gynecomastia.

But something that I noticed before the gyne came about was that my testes had shrunk a bit

Testicular size is a good guide to testosterone levels, with smaller testiscles often meaning few leydig cells and with it lower testosterone. This is why endocrinologist often measure testicle size with an orchidometer when considering testosterone deficiency.

I think I also had zinc deficiency as well when I finally quit drinking, because my eyes would hurt around bright lights, then I started taking zinc every day, and that immediately went away. Also, the 1st time that I took the zinc tablets, I felt strangely energized and "odd" for a couple hours.. I don't know why else that would have occured, other than because I didn't have enough zinc in my system.

Zinc acts as an aromatse inhibitor in some men. This means that it prevents the bodies testosterone from being converted to estradiol. It means that zinc supplementation may increase bioavailable testosterone in some men.
Testosterone is not just used for building big muscles, it is vital for energy, stamina and a whole host of other factors. It is therefore not surprising that you felt invigorated by taking this supplementation, this is most probably attributable to a greater fraction of bioavailable testosterone.
If you are deficient in zinc this supplementation may even increase the size of your testicles, as reducing aromatization of testosterone to estradiol will alter the negative feedback of estradiol on the (Hypothalamus pituitary testicular axis) HPTA. This is because reducing estradiol leads to an increase in the messanger hormone (Luteinising Hormone) LH and increases in LH tell the testicles to increase leydig cells. The result of In increasing leydig cells is an increase in testicular size.
