Technically even people without testicles aren't dependent on testosterone or estrogen. It's rough but you have some hormones from adrenal glands.
Court Eunarchs have been a thing across history and many lived long lives. There's all sort of additional health complications like osteoporosis. But it's not like you drop dead without estrogen or testosterone.
Even today there's people due to hormonal related cancers (prostate or testicular, breast or ovarian) who have to be deprived of sex hormones either chemically or surgically to treat the cancer and prevent it's return.
Milo Edwards has this bit about how foot fetish guys have the worst PR for what is kind of a mild fetish and it's so bad you can't compliment or massage a foot without being suspected.
I'm not a foot fetish person but I'm not anti it. Feet stuff synthesises well with a lot of BDSM which I am into, being stepped on, dismissive foot jobs, tickle torture, worshipping through foot massage etc
It's kind of like piss. Not my thing again but I'd do it in a BDSM context because it fits well, being tied and needing to piss, being forced to drink piss, piss waterboarding etc.
Er do we need CW in an already NSFW thread?
