When I read this story, I laughed out loud at the "prostate/non-prostate owner" terminology. They are so far in the bag for fake "social justice" that they can't even acknowledge basic human anatomy. The prostate secretes seminal fluid. It is, by definition, part of the male reproductive system.
Of course, this is the same mindset as the media that breathlessly reports every time there's a "pregnant man," who of course is really a woman who is undergoing gender reassignment and still has intact female plumbing. Cosmetic surgery does not a medical miracle make.
And no, by focusing on the SJW silliness, I'm not ignoring the fact that an article about anal sex is entirely inappropriate for a teenage audience.
