there's several, but one i had forgotten is that it needs to be deeply washed _several_ times before wearing.
i've been wearing a a bathing cap when i get home from work to get used to having latex on my head, even to the point wanting to be of being able to sleep with it on. so i also bought a molded latex hood off ebay for about 20$ and after ten days it arrived so i tried it on before i left for work this morning.
its a thickish latex with less stretch than my panties for example. anyway after what i considered to be an unreasonable wait (i've had tuff from englands faster) i tried it on.
its tight for sure, just can stick out my tongue and and see through the eye holes. a bit of work to put on for sure and way way more compression on my pretty head than the bathing cap i'm practicing with.
then i noticed the stinging... and took it off.
my face looks like i've had a bit too much sun. there's some sort of chemical used in the making of it thats not good on human skin. its lessoned now but its still a bit sore. just like a sun burn. hope its ok tommorow. i'll put some sun cream on and see if that helps.
and i'll wash and rewash the hood about four times before i dare put it on again.
thats one, i'll continue the list later but i think i really need to get a proper hood. :-(
