Okay, this will probably be lengthy, so a TL;DR:
In functional terms, it's *not better* in terms of pleasure, but masturbation is impaired, if you're into that or if you don't use your foreskin normally, that's unchanged//better, otherwise, it's the same thing. In the psychological terms, it might be better for you, playing off the thought of "having everything I was born with" // being natural, but that's a you thing. In the looks terms, again, its a you thing. In the monetary terms it's better as you won't harm your pockets for the same end-result, but unless you're from the U.S. it should be cheap. With that said, there's no real better or worse, there's personal preferences and psychology behind it, in my own personal tastes, not all penises look *fine* when retracted just like @nunchuck said, I don't really mind looks at all though, I'm in for the moment, but it's something I take notice, if you got a pretty dick I won't deny you got a pretty dick and might compliment, but the other way around is also true (albeit I will keep it to myself). At the end of the day, it's your body and you do to it whatever you want, just don't let anyone talk you into doing something, and there's no real difference either way.
Now to elaborate a bit on my take on things:
I stayed retracted from 2016 to ~2021 after a frenulum tie I had no issues nor need any devices to stay retracted, I only covered myself during masturbation for the split seconds of the gliding motion. After those years, I would spend time remaining covered and uncovered at my heart's desire, albeit I disliked being covered.
I circumcised myself this last Saturday at 2 am, I won't go into details of how as I don't wanna encourage people to do it, and staying retracted definitely isn't a "training" in any way shape or form with this being "the real thing", that thought is just stupid, and as a fact, I kinda did it out of nowhere just because. I did it out of fetish pretty much, so yeah.
Here's my counter arguments to the original post's with my opinions attached to it, within logic applied to them:
✮ Circumcision, as it is, is reversible to a certain extent. Restoration is a thing, and while sure, you won't have the "original" thing, it will be pretty much the same, personally the so claimed "millions of nerve endings" never did anything for me (and I experimented a LOT). So just like you can just un-retract, you can spend a few years using those devices to get skin back there. So points 1 & 2 of the original post don't really click to me.
✮ I'm bi and more into men (and bottom while at that), with women I believe its more of a technique thing but sexual matters are more psychological thing to be honest, it reads to me as if you got a fetish about being retracted and/or the women you've been with found it interesting. I both own and use textured dildos and have a few girl friends in that same situation, and it kinda has to be REALLY textured to make a difference, I doubt your foreskin is way thicker than your glanular ring, specially with the motion that tends to extend it, so that's why I take it with a huge grain of salt and dismiss it as a mental thing.
✮ Looks are a personal taste, you might hate foreskin, you might love it, and same applies to any and all partners you have you might love/hate theirs and they might love/hate yours, quick reminder here that not all dicks look the same, some can be prettier than others retracted (or covered for the matter) but it's a *you* thing, it's your body and it's up to you if you go covered/retracted/circ'ed. Personally I find that there's a certain charm to it, and I actually like the 'action' of uncovering and find full on exposed penises a bit vulgar. Also a quick thing: your glans curving thanks to your frenulum is a medical issue known as Frenulum Breve (short frenulum), if it doesn't cause you pain, its nothing to worry about, but it's not *normal*.
Now replying to other points:
✮ Cleanliness: How hard is it to pull back and rinse? Come on.
✮ No-cost: Can't argue with that. You CAN take the DANGEROUS route to circumcise yourself and save those few bucks, but you can end up causing serious damage upon yourself. And again, just because you can doesn't mean you should. Circumcision costs vary greatly from region to region (and country to country), in mine, you can get it done from ~200 usd to ~1.2k usd (you can even get it for free if you're willing to wait in a queue on our public health system, but I would much rather go to a private doctor and talk it through honestly, trust that more), and medication is cheap around here, barely adding 30 usd to the total cost.
✮ Non-obvious body mod: It's funny that this I read this now, literally yesterday I was thinking whether circumcision is considered a body mod after deciding I wanna get a split tongue later in 2023, and was surprised to find it isn't considered one. I don't see this as a pro or con, but I will say: No, people won't assume you're cut. I've been into this for nearly 10 years now, and I'm yet to see someone that is passable as cut. Take it from Japanese men, people just know they're just retracting. The only way I can think someone can be passable as cut, is if they retract their foreskin and don't unretract it AT ALL for years on end, so it basically becomes redundant and just shrinks into the shaft, but even then there's limits to that. Or if they were born with a shorter foreskin I guess. It's the wrinkled pattern that gives out you're not cut (and it's not like there's any benefit to that). But again, looks are a personal preference, and you have to pay attention to someone's dick to notice that. And personally, I've never heard of foreskins that conveniently naturally retracts, I don't know how I would react if someone tried pulling that on me on the spot, but I would probably chuckle, not in a rude way, just as a "oh dear" knowing they're probably embarrassed.
✮ Circumcision causing pain: I mean, I've read a few cases FROM anti-circumcision groups, but most of them were related to infant circumcision arguing that too much skin was cut so when they hit puberty and their penis grew, erections were painful. I guess those just fall under botched ones, and I am against non-adult circumcision either way.
Now my opinion: There's no better or worse, there's preferences, it's your dick, it's your body, do with it what you want and aim on pleasing yourself more than others. To me, retraction/circumcision is a fetish of denial(as in self-pleasure) and vulnerability, that's all there is to it.
