There's trans humor that doesn't reference the trans experience?

Days sounds like a bad idea for anything, really.

Eeek days is crazy

But i agree, no matter what you do it always ends up a little tender at least

But try baby oil, like soak that tape in it. Itll come off much easier

Tape is used for that and to keep breasts flat against the chest.

Duct tape is not used.

Back in the day, duct tape was used for that, as well as some breast tissue positioning and immobilization.

It was never a good idea, even for short term use, and it would usually only be people fairly new to controlling their body that would use it. As soon as they made friends that had experience, they'd usually switch to other methods. There were some drag queens that preferred it for stage work, but that's a different thing entirely even though the use of duct tape in those circles does linger at times because it's cheaper when you're using whatever control product you choose more often.

But, yeah, the use of tape in one form or another goes back to at least the 60s that I know of, though duct tape wasn't always in play afaik. Not like I'm a historian, I'm just loosely familiar with bits and pieces from immersion in the old solo school lgbt community. Hell, mostly from when it was mostly just lgb tbh, though I try to keep up on basic info for when someone in my life expresses a need/desire for info to get them started.

And on that note, it's important to remember that duct tape is maybe the worst possible choice for top or bottom control. There's old tricks where it can be used in very limited ways to give a little tactile shift in small patches, but I sure wouldn't recommend it despite it still being done.

Transmen (female to male) use not duct tape for whats called binding ie taping booba down to be as flat as possible

Transfems (male to female) use not duct tape for tucking, which is a bit more involved than what you said but yeah its exactly what you think it is, genitalia taped down again to be as flat as possible

Kinesiology tape is a good tape to use for both of these purposes

Duct tape for chest, idk for the trans man Surly it isn't related to the hole

Edit I don't speak trans so Idek
