Subject: Why my hair rises on one side of my body when I get a kiss in the ear?

The hair on my skin rises only on the right side of the body when I'm kissed 
on/in the right ear and vice/versa. Why is this? What are the 
neural pathways involved and what is the function of this phenomena? I 
understand that the sense organs like the ears are extra sensitive for 
protective reasons (i.e. insects can crawl into the ear), but I think this is a 
strange reaction, this asymmetrical hair rising.
