I'm Andreas, 26 living in Berlin.
I'm bisexual, after a long relationship with a woman I took the chance to live out my unfulfilled fantasies of being in a discipline relationship with an older man.

After 3 years of experience, I am convinced that the only way to experience true discipline as a man is by being kept in chastity. As long as you can connect orgasms or sexual pleasure to the discipline you receive, during or after it, the sexualization will ruin the discipline. Take the orgasms away and you will be retrained to see spankings and canings as tools to enforce discipline only.
I have been in chastity for 2 1/2 years, with periods being minimum 7, maximum 21 days.

Chastity makes good boys out of bad boys and even better boys out of good boys. It is the only reliable cure for porn or masturbation addiction. It will help you get rid of unhealthy and unrealistic sexual fantasies. It helps you to refocus your time and energy to better and productive things.

Chastity means no orgasms without permission.
Chastity means no masturbation, EVER.
Chastity means TIGHT penis cages that suppress erections efficiently.
Chastity means knowing how it is to cry yourself to sleep in frustration.
Chastity means orgasms are a reward, not a privilege.

Chastity is blessing that has changed my life for the better.

EDIT:
As people have asked in private messages repeatedly about certain things and some questions were good and thoughtful, here some Q&A:
The penis cage I am in is the Jail Bird from Mature Metal. Secure, easy to clean, discreet, a very good investment. I came across a blog called malechastityjournal a few years ago and reading the praise the jail bird received I chose it as a permanent replacement for my too big CB6000s and it has been an eye opening decision. The device and the refitting when you experience shrinkage over time when kept chaste 24/7 costs a fortune, but it is worth every penny as it will help you due to its unmatched efficiency in preventing all attempts of erections.
Yes, I do highly recommend custom made cages to fit your penis size as with space for the penis to grow the effectiveness of chastity is compromised.
Non customized cheap cages will be either too long or too thick, allowing erections.
No, I do not have a Prince Albert or similar piercing, the jail bird is very reliable without this extra security as I can only get out with a lot of effort but I can't get back in without the lock being opened to I can't cheat without being caught.
No, I am not a sissy or am feminized, I am bisexual and do pleasure my disciplinarian in every way he wants but I am respected as a man. Well, as a bad boy who need guidance and discipline, but nothing that degrades me as a man like having to lick up my cum after I was milked or similar things that happen a lot in FLR.
Yes, I have been a massive porn addict and used to masturbate daily, binge watching porn at every given opportunity. I have not been allowed to masturbate in 16 months. I do still watch some spanking porn and mostly chastity videos, preferably home videos as the professional material is completely fake and a masturbation fantasy. Chastity first and foremost puts and end to masturbation and will remove you from your fantasies, the harsh reality of it is worlds apart from this "sexy mistress teases you" nonsense. However, as I am locked I cannot masturbate to the videos so it's not the same and it's more like reading a book with some erotic content now than reading a porn magazine with mostly pictures. And to be honest, videos that capture the reality of chastity are extremely anticlimactic, how can you capture the reality of being in a cage for 7 days and the only times the penis cage comes off is for washing and some tease and denial to make sure everything stays in working order and you keep aroused so the chastity with keep its effectiveness.
Yes, I am truly happy being kept chaste for various reasons, but I don't know if I will stay in this situation forever as I am bisexual but prefer women as relationships sexual partners over men who I prefer as authority figures and disciplinarians.
A future girlfriend of wife would have to keep me in chastity to keep me from relapsing to my porn addiction I guess, but I have a hard time getting my head around a woman spanking me in a similar authentic fashion as my disciplinarian does now, I think the best scenario for that would be a male disciplinarian punishing me while my girlfriend or wife witnesses or supervises the spanking. My disciplinarian is over 30 years older than me so there is a very clear hierarchy, I would not like this dominance in a relationship with a woman my age. So no, I don't think a female led relationship is for me, keeping me chaste would be a mutual effort for my own good though I expect that I would be unlocked a lot more often than now for sex, but locked in again after so I don't get the chance to masturbate.
This was a very good question!
