Pee shivers?

Pee shivers? 

You know when you are peeing and have a sudden whole body shiver like you are cold.  I get them randomly, but never know when it will happen.

How many people get them?  Any particular circumstances?  Men only or women too?

[Bacardi 10,136]

Yes! I get them all the time. Especially if I'm sitting on the toilet and am about to pee, but I decide to hold it anyway. The dying need for it to come out mixed with the arousal it brings often sends a shiver up my spine and makes the hairs on my arms stand up.

I get them often. Particularly if I’ve held in a long time and release it.

I get them when I hold my pee for quite a long time. Not so much when actually peeing

I have from time to time, and there is no explanation to why, medically speaking
