I have never been sexually aroused by the idea of v*, but I would like to share that when I was really young (like 9-10 years old, a few years after my emetophobia manifested), I would confuse sexual arousal with the anxiety I'd get during a stomachache. If you think about it, an anxiety attack and sexual arousal have similar symptoms. Shortness of breath, 'butterflies', etc. I can definitely see how some wires could get crossed in the brain that would lead an emetophobe to also be an emetophile.
