Ok so in my experience, semen retention makes my balls 30% larges after about 2 weeks, they keep getting bigger as I continue but far slower from this point on.Another thing is massaging them regularly can make them larger too but to a lesser degree.
This is all I know about changing testicle size, ejaculating frequently can shrink them to a half size in my experience compared to when on SR and regular massage.
I would never pump them as that seems dangerous to me
That is consistent with the most current research, but no human studies have been conducted using multiple ejaculations within a certain timeframe to gauge the body’s response. I’m operating on my own anecdotal evidence that I had a higher sex drive (which is associated with higher T levels) when I was ejaculating multiple times in one night. After becoming accustomed to only getting sex once a month, that drive and performance was lost. Most would say that it’s due to age, but I’m self-evaluating the relationship between short-term ejaculation frequency (by ejaculating multiple times in 24 hours or less) and the resulting sex drive/perfomance caused by the hormone cascade produced by it (despite my age). No studies I’ve read have been conducted in this manner.
I have a girlfriend who is very sexual. I’m not about to abstain for weeks or months. But I will follow up sex with masturbation (or more sex), followed by a short period of retention, to boost my drive. Abstinence/SR is not a lifestyle choice that I would ever adopt, simply because it defeats is own purpose. To have a higher sex drive, bigger balls, bigger penis and not use it doesn’t make much sense.
