Some recent reports (for example: https://www.nhs.uk/news/cancer/frequent ... ncer-risk/) suggest that men, who ejaculate more than 21 times a month, are less likely to contract prostate cancer than those who ejaculate fewer than seven times a month.
On the other hand, other reports (for example: https://www.medicalnewstoday.com/articles/319536.php state that men, who ejaculate frequently in their 20s and 30s are more likely to contract prostate cancer but frequent ejaculation after the age of 40 may reduce the chance of prostate cancer.
None of the reports make any distinction between ejaculation by sexual intercourse or masturbation.
So, to be on the safe side, lock your man up, perhaps with occasional releases, until he is 40 an then have him fuck your brains out for the rest of your lives.
Of course, these reports are based on statistics only and have no medical support.
Is chastity safe?
Re: Is chastity safe?
Locked til 40 and then fucking your brains out sounds fun, but the reality is "use it or lose it" for most older men I've talked to. After years or decades of chastity play, your wangdoodle is so used to restriction that erections can be ... difficult.
So many people in the same device ...
