I'm a strong swimmer, and I enjoy recreational lap swimming in pools. I enjoy sitting by an outdoor pool on vacation, and swimming to cool off.
But, I detest swimming in natural water (lakes, rivers, oceans, etc.). I will go out of my way to avoid it.
I'm not afraid of doing so. I've never had a traumatic experience. My parents didn't drown. I'm not afraid to go over bridges. I've enjoyed sailing and motor boating. I've even swam in the ocean, lakes, and other bodies of water without incident.
My distaste for it is more based upon the feeling I get while in the water. It is not at all a panicky feeling. It is not fear. I just feel unpleasantly dirty and disgusted. I dislike the feel of stepping on seaweed or mossy bottoms. I hate sand, and particularly wet sand.
Is there a word to describe this level of irrational hatred for something? People always think I'm describing a phobia, but as I've said it's not fear based. I want a word to describe my utter revulsion that carries the same gestalt as phobia but, distaste rather than fear based.
