If, after puberty, you can't easily retract your foreskin over the head of your dick (it also shouldn't hurt), you have a very unhygienic problem called phimosis.
It can be self cured with regular stretching but sometimes you will need a doctor to prescribe a steroid cream to assist with this, the worst cases can require circumcision.
I had this problem until I was 19. I couldn't retract the skin because it was so painful. I had a very short frenulum so I couldn't even masturbate. I went to a doctor, he said I should circumcise. DO NOT circumcise your skin. There's a much simpler operation where you just cut and remove the frenulum. I learned this from Google, the operation lasted 15 minutes and my recovery was extremely fast
It's actually the whole penis. The glans is only the glans of the clitoris. The other parts (internal) of the clitoris, in the case of a penis, are the whole shaft.
It was that or no sex at all. At least I got to keep my skin, so the sensation stayed the same. When you are circumcised you loose a lot of feelings down there
Yes, someone I knew had this. He actually bled because of his foreskin ripping when he lost his virginity when he was 30 or something.
We were on holiday with a group of friends at the time, we shared cabins in groups of 6. One morning we came downstairs and there were sheets hung up in the living room. We asked what happened, he said he had a nosebleed and bled on the sheets. Later we found out from the girl he was with they wanted to have sex, he was a virgin and when they tried his foreskin tore and bled all over everything. Of course by the end of the week everybody in our extended circle knew.
They wound up married, even though they were 10 years apart in age (she was 20 at the time, as were most of our group, he was the older brother of someone in our group). Now he's a fat lazy fuck without a job and the wife has to take care of their two kids, the house and has a job. They still married though, even if the wife's complaining about him all the time. So all's well that ends well I guess.
A bit TMI but I grew up in a fundamentalist Christian household (aka super sexually repressed) in an abstinence only sex education state. My parents decided not to circumcise me or my brothers, my dad is apparently circumcised because neither of them told me how to clean down there or that foreskin even goes back. It was never once mentioned during any sex ed, anatomy, etc. classes in school. I had no idea that foreskin was even supposed to go back or that merely getting it wet in the shower wasn't good enough until I was 17. I had frequent irritation down there and I just thought that's how it was supposed to be. 4chan of all places taught me about phimosis and proper hygiene.
Not to excuse the guy in that posts' shitty behavior but for some people they are told literally nothing about their bodies or how to care for them and so long as it doesn't put you in the hospital, it's something you're unlikely to learn out in the wild. There may very well be people reading these posts that are learning how their genitals are supposed to function right now. I was one of them at one point
Maybe it's fine in your case. For some people it's so tight that their pee shoots out sideways, any amount of self care is not going to be able to clean sufficiently under there.
Ok, we'll advise young men to pressure wash their bellends instead of seeking treatment for their severe phimosis, and if they have to sit down to pee instead of using a urinal because they'll piss all over, then oh well.
It can also lead to priapism if you somehow (through great pain, I'd imagine) manage to retract it and the tight part becomes stuck during an erection. If not treated in time the lack of circulation leads to necrosis.
Not being able to retract it has nothing do with being unhygienic - poor self-care is what is what is unhygienic. Just use a shower head and mild soap if necessary and you're all good.
Source: I have it, I get a checkup done every year and it's been fine. No buildup or issues whatsoever.
Maybe it's fine in your case. For some people, it's so tight that any amount of self care is not going to be able to reach the parts where smegma collects.
