From the view of this and your other answers in this subthread, it seems that this is more a problem of yours yourself than one in general. So to be somewhat helpful: if it is an actual phobia that is influencing your life to the negative, you might want to consider talking to a therapist. These revulsions absolutely do not have to influence the rest of your life - there are ways of dealing with phobias (to some degree at least). I am aware that health care recommendations (#) (for US americans, as I assume you are one) can be hit and miss because of the costs involved but I wish you all the best! There's no harm in asking for help if you're in need of it.

(#) I am not a doctor, so this is can not to be taken as professional advice/recommendation but rather as something that common sense dictates.
