How to never have er*ction again without other harm

Hi @confusingthings, Great choice of member name. Your "a few things first..." kind of sets the tone for my response and I hope you are not offended. There are a lot of things in life that are confusing and sometimes it takes a little time and patience to learn how to deal with them. It is absolutely great that you are reaching out to learn what can help. Your question is well thought out and hopefully there are some young men close to your age searching for answers similar to you that can share their experience. I can share a couple of things I found that may or may not answer your question but hopefully provide more information and generate more thoughts or questions.

"Teenagers and young adults are more likely to get random erections, though they can occur in adult men too. Random erections that occur only in the morning are normal in many men, regardless of age. Occasionally having trouble getting or keeping an erection is not cause for concern either. However, if you notice a lot of changes in erection frequency or ability, it could be a sign of erectile dysfunction (ED) or another underlying medical issue."

Have you thought about discussing your concern with a doctor?

1. I'm not confused, I know about these things
2. I've seen all the methods online for getting rid of an existing one, that's not what I'm looking for. The point is for one never to start. Ever.
3. I don't care how normal it is, I still want it gone.

None of what you said answered the question.

@confusingthings I just wanted to jump in here. I was a nurse and i worked with a great urologist. He dealt with problems like this so I would suggest finding a good urologist at a major medical center. I hope this helps

I wonder if, in the end, @confusingthings has found something useful.
I’m in a similar situation too.
I’ve tried something to just end the nightmare of having this unwanted “physiological mechanism” (nothing harmful), which is not the “wait until you’re old” method, and it has been a waste of time.

Have you asked you doctor for a testosterone test?

Unfortunately the original poster was from 2023 and since he has not recently posted its doubtful he will. Maybe he found a solution or realize its normal. You should check the posting date of the post you wish to respond to.

@jenatsky

Yes, thank you, I'm well aware that the post is from 2023: I hadn't missed it. The point wasn't the date, but the attempt — because sometimes, even years later, someone can find a solution and share it.
As for 'maybe he's accepted that it's normal,' I assure you that for those experiencing this, there's nothing normal or acceptable about it. Dismissing it like that isn't very sensitive.
I tried asking anyway, because I'd rather try than give up.

Hi ! I've searched for the answer to this question many years ago, and i understand so much the frustration in @confusingthings ' introduction, as i've seen Way too many times in various places over the web, very demeaning and nonuseful replies.
i've actually just woken up in the middle of the night angry at such past replies from a similar thread on reddit, with the intention to right things, with the knowledge i now have.
Yes, confusingthings may not be around anymore, but as @simo5 has mentioned, people will keep asking the same question and look for it again in the future. This thread is currently at the top of internet searches, so i'll try being the one that i was desperately looking for in the past, by creating an account just for this.
First thing first, you have my deep empathy and understanding, and i'm sorry you have to live through this.

Then,
Surgeries: as @becsbuddy has mentioned, there are surgeries which can be non-invasive and not even removing anything ! (i've just learnt that today, to be perfectly honest.) i can't vouch for it as i've opted for a total removal a while ago, but apparently, with notably penile denervation or cavernous nerve resection, you may put your organ to rest permanently. Just a section of nerves if i've understood. i have to say that being finally free of these pesky erections after decades of suffering is extremely liberating, and i feel like i can finally heal in peace.
i guess i'll quickly mention stuff such as "if you ever want children someday, you can freeze your sperm for a cost before to potentially loose your ability to reliably produce it", just for good measure.

Now i'll keep listing things trying to be exhaustive as possible (to my knowledge, i'm sure there's more) and you have mentioned the following thing,
Drugs: i didn't try much, but to my knowledge, it's a total gamble, and with secondary effects. Getting those from the snuggymom website:
"Baclofen: Muscle relaxant that decreases reflexes related to erection.
Dopamine Antagonists: Lower libido by altering brain chemistry.
Methadone and Other Opioids: Can reduce sexual function but carry addiction risks.
These drugs require careful medical supervision due to side effects and dependency potential."
Numerous are the antidepressants that list the potential effects, but effects are never pick-what-you-want...

Hormones: the original poster seem to already know about how antiandrogens and the absence of hormones can lead to health issues such as osteoporosis, but i'll mention it for others who come. If you want to remove your testosterone, ideally it's paired with an estrogen replacement. Which, i'll unfortunately inform you, is not a miracle solution against erections... i've been taking HRT for years estrogen included, and they Never made me know peace about this topic. it did have a lot of other effects however, but that would get off-topic.
I'm not saying it cannot work, as apparently, lots of transfeminine people experience penile shrinkage and such, but yes, apart from the surgery, as everything else, it's a gamble that didn't work for me.

Physical practice: speaking of trans women, there's the practice of Tucking that i've read did work for some. its main purpose is to hide the bulge, but it apparently can limit the blood supply that activates erections. it's basically a sort of genitalia folding, maintainted in place with tight underpants ; there are guides online.
Unfortunately Once Again, not always a solution that works for everyone, as it did not for me ! but it's worth trying. my theory is that people who successfully do it, either have a "handy size", or it doesn't instantly activate a fight response from their penis - which is what we want to stop ! So, maybe if you manage to tame it before it acts up somehow... May put a strain and pains to insist a lot.

Accessories: some people have mentioned using rings and/or chastity cages, again to limit the blood flow. Of course, not all models are equal, especially if they're not all meant for the same "use"... but some are apparently adapted to be worn on an extended duration of time, or are discrete (such as "null" models meant for bulge hiding.)
i can't personally tell you if it works, as nobody had informed me about this practice before i chopped off the whole deal, but i really wish i had at least tried, to spend better years until the big event. Well, you can look up other people's experiences.

Mental stuff: i've read that high anxiety and other emotional excitations may trigger erections... i suppose that the anxiety produced by mines probably just ended up feeding a feedback loop and making it all more disastrous... Trying to lower your anxiety may not be a miracle solution, but it's always good to take in general.
Over time and with the mental space to heal genitaless, i've personally eventually found out that there were some traumas behind how problematic these body reactions were to me. Certainly Not saying there's anything wrong with you too of course, being asexual just happens... but it can be worth thinking about it if there's deep sex repulsion (not that finding it out can stop invasive erections though...)
In any way, the surgery was right for me, and is the most secure way to end all of this ordeal.

I hope this reply will have been useful to people like us. If you've just typed this question in a search engine and have found us: know that i see you, i feel your suffering, and i love you as you are.
And regardless of your gender, don't hesitate to check on the trans girls in the future, in case they could have found out new safe and efficient ways to fight those inconveniences, as i'm convinced lots will keep trying hard.
May you find the peace you're looking for.

I was interested in what I perceive to be an intense response. Perhaps some medical/psychological evaluation is in order to rule out any problems. Erections can occur at any moment, spontaneous erections, specially when young. Painful? I don't recall hearing men saying erections are painful. Not wanting to have an erection ever again is somewhat extreme, in my opinion, especially at a young age.
Give sex a chance. It's great!!!!!
