Do a google search of personal narratives for nearly any usually fairly mild illness, condition or odd medical problem you care to mention, or even a google search for what it was like to take X medicine (said medicine being something very, very commonly prescribed to millions of people per year without statistical evidence of frequent severe problems and side effects) You know what you'll very likely find? A ton of horrifying personal accounts with all sorts of worst case scenarios and unexpected terrible things that many people will be posting about having happened to them. This is one of the big reasons behind the now old joke that if you google search "persistent cough" you'll end up diagnosing yourself somewhere between super cancer and mega HIV...
The point i'm making here is that these sorts of self reporting-based accounts massively bias towards awful outcomes, despite being statistically minor in broad terms of probable outcomes. Poeple who got sick and felt fine after recovering have a lot less incentive to bother posting about it.
I suspect you're seeing a lot of this with what you describe and especially if your linked source is a damn reddit thread where exactly the sorts of people who had unusually bad things happen to them after recovering are likely to go. This will likely apply even more so given the immense media attention and public fear around COVID. I can only imagine how many recovered people are either experiencing psychosomatic long run symptoms or attributing any new bad thing they feel from of some unrelated cause to the virus post-recovery despite no connection between the two. (you mentioned penis pain, well, a person can still get herpes or chlamydia some time after having recovered from COVID, for example)
Sars Cov 2 is a coronavirus, one among several of a similar type. We're still learning much about it and doubtless there are going to be many complicated patient outcomes from some among the many millions who recover from it, but it's not some insane new super disease from the bowels of hell. Let's calm the alarmist hysteria before jumping to unsubstantiated claims about widespread terrible shit.
You mention literature backing up your claims. Well, link to it, and let's see if it's statistically significant or based on a small number of reported cases out of (so far) millions of recoveries.
Finally, a bit of anecdote of my own: I personally know 6 people who have gotten the virus and recovered. All of them now feel more or less okay several weeks after recovery. Two of these people are 91 years old by the way, making them an exceptional case but worth mentioning.
