I actually think your approach is the ideal one to cover trans people in this. You don’t treat them in any bad way but still give the ability to participate if they are into it. I find your argumentation for that also very well put and I don’t think it’ll need to be changed. My additions about trans women anatomy where just interesting things to consider if ever doing this with a trans woman, it doesn’t need that to be included.
In the end, nothing is ever really written into stone. This can serve as good inspiration for someone, but might need some adjusting for the specific person, as is the way with kink. Your text is actually perfect for considering trans people in this and if they want to participate, you adjust the little details to them.
If 2 consenting people want to try this out, the length measurement can be arbitrarily set to any amount that will result in the desired outcome. I think it works well and trans people can still easily fall into your 12cm measurement (especially with the way it’s written, they don’t necessarily need to be erect for measurement, which can be harder for trans women and would serve as a new angle of humiliation)
They do. Without enough testosterone, the body will stop doing this. More interestingly, (and somehow no man in the world knows this) men get erections at night when they sleep to keep their penile tissue maneuverable and stop damage to the erectile tissue even if they don’t have sex or masturbate. With testosterone blockers, this stops and you need to do it manually otherwise you risk permanent damage (which is guaranteed otherwise). This is called penile atrophy, which makes any form of erection very uncomfortable and painful. As fitting as that sounds, kink should never play with lasting damage like that.
I don’t see it very differently from using a dildo, which was kind of already framed as feminine, not manly form of stimulation. It also opens the possibility of the vibrator being fixated to a chastity cage and “forgotten” to be take of. I see lot’s of potential for humiliation with it
I think it’s the perfect approach and doesn’t really need changing. It’s just nice to see someone considered trans people so well in a kink writing
