I've experienced this all my life. It doens't happen all the time, but it does happen quite often. After you urinate, your body shivers or shakes for a second or less. Friends have told me the same thing happens to them but I've never heard this happening to any females. Does this happen to you?
there is alot of stored heat in the pee when it is released it makes you cold for a second internally.
Wow, now that I think about it, I have those sometimes. Probably around 25% of the time, but I still feel a shiver right after it's all out.
