i've read this thread a few times...just thought i'd put in my two cents....
i don't understand how you can be affected by both, but i know you can because i am....
for me, i'm more scared of others vomiting than i am of myself...but the longer i go without vomiting, the more the fear intensifies.
i know that in real life, i can't stand the sight or sound or even the thought of it getting on me..guuhross!!(lol)...
anyway, i can watch tv or a movie or even read or talk about it and it causes that adrenaline rush.... doesn't bother me one bit
i think for me it's more fantasy than fetish....because if someone were to actually throw up near me, the panic would set in and i would surely be out of there fast....
best i can explain it...
