I am often asked whether penis shrinking, through the long-term wear of progressively smaller chastity devices, is a real phenomenon. How small can you shrink a penis? Does it have lasting effects and can it be reversed? What about erectile dysfunction?
I don’t have all the answers, but here’s my attempt to share what I have seen in my time as a chastity enthusiast and practicing Domme.
What is and isn’t shrinking?
Penises are natural shape-shifters. Wake up on a hot summer’s morning from a dream about your sexy neighbour one day, and go Arctic free-diving in tumble-dried trunks the next, and it’s hard to believe you’re looking at the same appendage. Knowing if you’ve managed to shrink one can therefore be tricky. Shrinking within the chastity fetish is often confirmed by progression through smaller cages. For me, this can be a sign of shrinking, but it isn’t necessarily proof of it.
Even without chastity, most flaccid penises (excluding those huge and dense monsters you sometimes come across) can be squashed more than you think. I’ve flattened many to a mere slither in my tofu press (don’t try this at home and all that) but outside of the BDSM world too – serious squashing is everywhere. Transpeople seeking a more feminine or androgynous appearance may choose to keep penises compressed in various ways. You can buy specially designed straps and underwear for the purpose. Drag artists are famous for taping penises into impossibly tight spaces, and in some cultures inverting the penis inside the body is completely normal. Men of some hunter-gatherer groups in New Guinea, for example, keep their penises pushed back inside the body and the empty foreskin folded up, covered with a leaf and then tied with a tree-bark string to prevent anything from slipping back out. Replacing tree-bark string for a clit-clamp, a version of this practice has proven very popular with my SPH lovers.
If a tofu press can only crush a penis so far without destroying it, those who practice inversion demonstrate that pushing a penis back towards the body is more possible than many assume. Very short chastity devices achieve essentially the same thing – you haven’t necessarily shrunken it to get it in. Maybe you have, but maybe you’ve just increased softness, malleability, resilience to pain, or some knack of squashing.
For shrinking to have occurred the penis needs to not return to its former size when released. So does this happen when a penis is kept squashed, inverted or locked in a very tiny cage for a very long time?
I have kept many penises in small devices long term, and I have kept a submissive partner in chastity the majority of the time for the last five years (though unlocking regularly for washing, games, experiments and periods of clemency here and there). Before chastity became default, when cages of all sizes were just toys for ‘sometimes’, I could squeeze my partner’s penis into cages about as small as the Holy Trainer Nano (with some difficulty) but when they came off after a few hours, a few days or even a couple of weeks, his penis looked and felt exactly the same as it did before. It was after he was first locked for a long period – three months in quite a small cage with no unlocked erections permitted – that I noticed a difference. Not when he was soft, but when his penis tried to get hard.
Erect, it was softer, weaker and consistently failed to stretch to within about half an inch of its typical former size. Another three months in a smaller cage and the results were slightly more noticeable. But they didn’t keep progressing with each similar lock period, rather they seemed to reach a fixed point. Now I can keep him in a shaftless cage for four or five months with no unlocked erections permitted and when eventually they are, they’ll be pitifully small and weak for the few days he might be allowed to remain unlocked – sometimes appearing one or two inches smaller than before chastity.
I have heard a lot of similar stories from subs, Dom(me)s, kinky couples and people into long term chastity generally – keeping the cage on for several weeks or a few months without allowing erections does seem to reduce the size and strength of the erect penis and make a flaccid one more easily squishable into smaller devices.
A common explanation is that lack of full erections over time means the penis loses some of its elasticity required to stretch into a full erection when unlocked.
Does it Last?
In my experience, unlocked erections (if allowed to occur freely for long enough) do gain back some of their previous size and strength. Some report a full return to normal after a couple of weeks unlocked, others tell me their long-term caging has made erections permanently weaker and smaller and that no amount of time out of the cage seems to totally reverse it. It seems all this depends on the length of the lockup, the size of the cage, the age and health of the person and other variables. To keep the results of the shrinking it seems that most people would need to avoid spending more than a few days out of the cage with erections working to stretch the penis out again.
As for flaccid shrinking, some people are sure they’ve experienced it, but I haven’t seen obvious proof with my own eyes – perhaps its more difficult to notice if flaccid penises tend to recoil into terrified little stubs every time you whip them out of their panties– can’t think why that’s the case with me!
Getting More Serious
Everything so far has only referenced periods lasting a few months, with regular unlocking for washing and with unlocked erections allowed in between. What about people who never remove their devices, who’s cocks have been locked for decades in the tiniest cages without ever coming out even for a wash? I don’t recommend doing this however well you think you can wash with a device on or however keen you are to become tiny and impotent… but I know some people do it. The problem I’ve had with discovering whether these people have experienced more serious shrinking is firstly that the people I know in this situation won’t take off a device and break an uninterrupted period of years-long chastity just to measure – one person I asked told me he’d report on it once he reaches ten years but he won’t be taking it off before then (three and a half years to go). Not only that but many won’t keep it off long enough to test if the penis restores (please get in touch if you can share experience on this). The other reason is that since the idea of shrinking, penis atrophy and even impotence is so appealing to many people with the chastity fetish, so many stories are fantasies.
Of the few chastity device creators and sellers who discuss it at all, most maintain that lasting shrinkage and erectile dysfunction as a result of long term wear is a myth. Urologists advise that both are possibilities and warn against even overnight wear, but can’t point to recorded cases. Meanwhile the internet abounds with accounts of both permanent shrinkage and impotence.
What Is Possible?
It makes sense that long-term prevention of full erections will reduce their size and strength. Penises are not muscles, but like muscles and moving body parts generally, if they aren’t allowed to stretch for a long time they’ll waste. Certain degrees of erectile difficulties, at least temporary ones, don’t seem too far away from the diminished erections following a release that have been widely proven – especially if the person has other health factors to consider – but I’m yet to find anyone who I really believe has become permanently impotent from chastity alone. Whether it’s a genuine worry, a serious aim, or some combination of both, it doesn’t seem that this more serious effect is a likely outcome – even if it has to be accepted as a possibility on expert advice. Since restricted erections still happen inside cages or inside the body, long-term chastity on its own may not be enough to entirely kill off a sub’s ability to become erect.
Perhaps it is possible to use extreme chastity conditions to reach the point where an erection won’t ever fully return to its former condition and must exist in perpetual humiliation as a reduced nub. Maybe erections can be made so weak that a penis cannot physically fulfil a sub’s desires when the cage is taken off. All of these ideas are highly erotic and point towards the slow destruction of the penis’ sexual potential, the idea that when the cage eventually comes off, what’s left will be physically ruined. But it seems that this physical journey towards erection-elimination is limited for most people.
If a penectomy is off the table, or if the desire is to endure the experience – the journey through an incremental destruction of any future potential of the male sex organ, what may work better is a focus on psychological possibilities.
The Psychological Potential
Many long-term chastity wearers will say that without their device they don’t feel right, and this idea can be a lot of fun to explore and develop as a Domme.
I have one sub who I keep caged all the time, he is only allowed out once every two weeks to wash in ice cold water which he hates. Early on in the training, any signs of burgeoning erections during washing were stamped out (sometimes literally) and this is a person who is not turned on by pain. On top of this I continuously emphasise my dislike for it when he is not locked and my pleasure when he is. Over time this has associated only negativity with unlocking and especially unlocked erections. All his positive sexual experiences have been attached to the idea of being in the cage – it’s what he knows pleases me, it’s central to his submissive feelings towards me, it’s what earns him pleasure. In his cage is how he’s experienced the most erotic experiences of his life, and all orgasms since training with me . He and other subs I’ve trained long term have reported a sense that they need to go back in the cage whenever they’re out. When this state of mind is heightened they can’t get hard and they can’t cum while unlocked. Even with sexual stimulus and permission to get hard, they may not be able to.
What you create is a kind of controlled, artificial anxiety relative to a particular situation. It works as an erection inhibitor in the same way performance anxiety or other hangups might work to keep a penis small and limp in other men. Lasting effects of physical shrinking and weakening might be possible to achieve and I very much enjoy humiliating and teasing a shrunken little nub. But, for me at least, shrinking and weakening erections is less a physical way of ensuring the sub cannot achieve unlocked satisfaction or hope to impress anyone with their embarrassingly small(er) penis, but more symbolic of my control and what I’m taking away from them through my application of it. It’s often not the lasting physical effects of the cage, but the conditioning that comes with it which has more power to deny a sub the privilege of a functioning penis once released.
