Please note I can only give my personal opinion.

I'm the last person in the world who could or for that matter would judge you (given the bizarre nature of one of my fetishes)

Yours is an unusual one and in all likelihood Impossible to act upon ( for real)

You say "it's haunted you" are you sure it's a fetish? And not a phobia?

If it is a fetish, what about experimenting with role play, there are lots of people with medical fetishes that I'm sure would like to act out that scene with you.

Obviously your OCD may cause some issues depending on how it affects you.
