I would suppose it would depend on the sort of revulsion it was; if it seemed 'unclean' unlike rope of whips (I'd assume they'd be washed as part of maintenance), or if it was a disgust of preference (Maybe somewhere in your brain you didn't like the possibility that they were paragons of the so called 'vanilla' practices trying to seem "BDSMOMGWTFBBQcool")- or maybe it's a subconscious thing that you can't really will to know.

Whenever I see love-bites of other couples I feel/think:
1. A sense of commendation towards the couple, like a proud peer.
2. Thinking about my own love-bites (when the situation is right)
3. Depending on the situation (place, social context, mood etc); a small feeling of 'hey, you might want to cover those up for now'.

Now I'm no large deviant nor am I an expert in these ideas- hence why I periodically read from this forum to learn... I just felt that maybe another two-cents in your well of thoughts might help you explore your mind a little further, as I'm sure many of us try to do.
