Ignoring the weird pill-related part, the rest of your comment is actually sound. There are genuine medical benefits to be had, at least for males. I don't know if there's equivalents for women, but I recall reading a study that found that regular ejaculation significantly reduces the chances of prostate cancer later in life.
Everybody should be free to feel comfortable with their own bodies, IMO. Society's concerns should only matter when it comes to interactions with others.
It's complicated, but this might be considered a war crime. A key quote from the article:
The prohibition is presumably intended to make it less likely that a civilian or other uninvolved person will get injured or killed by one of these seemingly harmless objects. If you're booby-trapping military equipment or military facilities then that's not a problem, civilians wouldn't be using those.
