This hypothesis of yours may not be so far-fetched. I remember that Daniel Miller (person who had severe EC & is now cured) even stated that he kissed plenty of people when he had EC.
I too was thinking about this a long time ago but... how the hell could I even conjure up the courage to be with someone when my lips look like complete shit!? This is why I respect Daniel quite a lot. He just lived his life when he had the worst of his EC, thus thwarting the depression/healthy mental imbalance that EC brings along with crusty, swollen lips.
If this EC condition was an actual person then I swear that I would seek out & obliterate his ass. But--ranting aside--this is not the case now is it? Oh well.
If you have someone that cares for you enough I'd say, go for it!
