It really sucks that no one reached out and that you're feeling alone. (also, re: actual query: venetian carnival masks are both identity-concealing and allusive to carnival debauchery, so that could work)
Not quite the same idea, but I remember reading about women selling their used panties on the Internet and they could be anonymous that way? I think it might have been on Reddit but I am not sure.
with this suit head you'd only cater to furries -- it's too huge and looks too cartoonish and flashy and would likely distract the mainstream porn people -- but you could establish yourself in that furry niche *anyway*. just, be aware that if you use a fursuit head, this is your targeted market, but you can definitely work with that. if you want to aim more at the mainstream people (more competition, but it's a wider pool) a venitian style face mask and a wig that still leave your head with more human proportions would work fine. if you want to sell your panties it's probably easy to buy them by the lot for cheap, so long as they're moderately girly they'd still sell, they don't need to be super expensive lace. i mean, the expensive lace also sells, but you'd need to have gathered the money to invest in buying those, first. i'm sorry about your friends. that's really not fun to find out. :(
It is so weird to me that people become antis when they're old enough to have opinions and thoughts of their own.
