Sounds like you have a case of Netorphobia to me. I despise Netorphobic bigots who think they own their wife/husband.

Necrophobia 

Necrophobia is the irrational fear of corpses, not just those of people but animals as well. Also included in this fear are the people, objects and ceremonies associated with death such as undertakers, morticians, coffins, tombstones, cemeteries and funerals. In a another way necrophobia could also be used to mean a fear of the dead by a cultural group, that their spirits will return to haunt the living, causing them harm in some way.

In some cultures necrophobia would be totally alien as the dead are welcome among the living.

Netiphobia 

The fear of nasal irrigation, as practiced by jamming a diminutive watering can into one nostril, and angling the head to promote the flow of solution out of the fellow nostril. Blech.

Because I suffer from netiphobia, I will never again look at a teapot or watering can with affection.

Armed with the knowledge of my netiphobia, the villain tortured me with youtube videos of people using their neti pots.
