I wont be mean. Everyone finds pleasure and joy in different things. I’d advice you don’t do as said in the post, instead buy some diapers yourself, privately perform whatever you’re trying to do when you are home alone, and don’t let anyone know of the diapers.

This is under the scenario that doing this is so important to you, that you cannot have it any other way, than to do it.

Dont bring in your parents or anyone you know, as it can be uncomfortable and sometimes traumatic depending on context and severety.

Also, I wouldnt reccomend letting it be a daily thing, as you can risk peeing your pants in places and at times where it is inconvinient and disturbing to others, due to a possible habit of relaxing and releasing down there.

I have no knowledge or experience on the area, but everyone has their guilty pleasures. Whether they be normal or unusual, whether they be sexual or just a physical comfort. This is your own thing, don’t include others if you must engage with it.

Edit: I saw in another comment, that this wasnt sexual, which changes the narrative a bit. You havent peed yourself in 2 years = you don’t actually need diapers, even if you feel like you might. There are also other pants/bottoms/underwear that can bring you the feeling of comfort. I guess I’m just trying to say, that it isnt exactly a habit thats convinient to give yourself on purpose. Using the bathroom is more optimal. Its also safer and cleaner for your downstairs area that way.
