Well, there's been some interesting responses, but it seems the majority of people seem to have the reverse problem that I do - they like fireworks and don't like balloons when they pop.
Asking some of my non-fetish friends about this revealed similarities - they jump when balloons pop but like loud fireworks. It's a hard thing for me to wrap my head around because it makes me feel weird ... again... a feeling I haven't felt since I first started addressing the fact that I had a balloon fetish!
I think I'd be happy if I could just reduce the noise level and attend with my wife. Perhaps a combination of ear plugs and suitable distance will reduce my anxiety attacks.
(PS. Happy July 4, American friends!)
