This essay is very long. While it does accurately touch on high risk activities (multiple partners, anal sex, sex clubs) it is primarily a deep dive into the author's wildly neurotic relationship to sex and his total misunderstanding of what is normal or common. His specific medical problems towards the end are extremely not normal, yikes.
N=1 indeed, but I think many are unfamiliar with the anatomical details of certain extreme behaviors, particularly the injuries. It's instructive to see it spelled out, but population-level conclusions shouldn't be drawn.
It reads like anti-gay propaganda to me, which seem appropriate considering the site it's hosted on.
This just a gay conversion therapy propaganda piece. Please don't post this homophobic crap on HN.
I don't usually comment on votes on HN, but weirdly, this comment got two downvotes immediately after posting. And I guess no response because the posting of the article is indefensible.
