Welcome, David. We have discussed emetophilia here many times before. Some people are squeamish about it, but the consensus is that it is a variant on emetophobia that some people have to deal with. According to this poll, almost 1 in 5 emetophobes is emetophile, and I have seen other polls that about 2/3 of emetophiles are emetophobes. It's all related.
