Turned on by pooping?!

Well.

If you're actually serious - I suggest deleting this and rephrasing it into a more believable and approachable question.

If not - Quit it.

Either way - I like the Barney Stinson name.

What you have described is a type of Paraphilia (a disordered pattern of sexual arousal) called Coprophilia. Coprophilia involves deriving sexual pleasure from faeces; either your own or anothers, outside the body or coming out. It is an unusual Paraphilia, but well documented. I suggest going online to find out more about it, and maybe find a chat room with other coprophiliacs.

I'm not sure from your question if you are upset about this and want to stop, or if you just wanted to know what it was. If it upsets you there are ways of re-training your brain so that you are not turned on by pooping, but the treatment (orgasmic reconditioning) is a long process that requires help from a sexologists or clinical sex specialist.

Its called a fetish. Your specific kind is called "Coprophilia", or a "Scat Fetish".

It is common, or at least more common than you think. Other people have pee fetishes, consumption fetishes, blood fetishes, and all kinds of weird **** you could only imagine.

As long as it doesn't interfere with your life to the point that it harms you, you are fine.

Some people eat it. Can't say I do the same, but there are probably quite a number of people out there that are similar to you.

I don't think it's common at all, but some people do have it. It's called "coprophilia" and I have it as well to some extent...
