Wow. How very interesting. I actually hadn't heard anything like it til you said something. Lol. I know it's not funny because I'm sure it's real to someone. I have a VERY weird "condition" so I guess I can sort of understand this one. Man, it would suck to have the balloon problem though.
I heard about this via a segment on a tv program. I think they were interviewing a guy and followed him to a party for people with this fetish. I loved balloons as a child but there wasn't anything remotely sexual about my interest.
