Ok, first off, if you're going to reply to this, promise me you won't think of me as some kind of creep.

Secondly, this is something that I know works for me, but I don't understand why.

I find that I am aroused by certain musical instruments, specifically tribal drums, gongs, or deep pounding drums like the timpani.

Anyone else have this, or at least an explanation as to why I do?

When I began reading your message I don't know why but for some reason I thought you were going to tell us about you doing auto erotic asphyxiation or something LOL.

As for the explanation to your arousal issues, it has a name. It's simply called fetishism, no big deal and there is nothing dangerous or wrong about it. (Well as long as you are not aroused by chainsaws or guns or anything like that, you are safe).
