I think emetophobia is sometimes used (not just on here, but generally) as just 'does not like being sick' where I would think its fairly rare to like it as such. Though DH swears he enjoys it sometimes, but I assume he means in a 'it makes me feel loads better' kind of way rather than being something to look forward to when well 
I am emetophobic to the point where I have in the past fought it for hours and hours, even when I knew I woulf eel better if I just let it go. Migraines were a parcicularly terrible time for me, awful awful pain that I knew would disappear if I just let myself vomit but instead I would just fight and fight it, keeping myself in much more pain, and feeling crappier for ages.
As soon as someone says they feel ill, I cannot stay near them. If my children say they have a bad stomach, DH is on duty, or if he is not here, I will call my parents, siblings, anyone who could deal with it if it happened. I have in the past ran into dangerous situations by quite literally running away from adults who retched. Even typing this post right now is making me feel wrong.
I have felt this way as long as I can remember.
I have not vomitted in 14 years now, and counting.
