Speaking of repeating.. Have you ever listened to people having sex?
1. Pant pant (repeat over and over at varying levels of intenisty)

2. "Do me in the (insert appropriate orafice here) baby" rinse, repeat

3. "don't stop..just like that..yeah...right there...holy shhhhheeeeeit"

For me it is totally cerebral (with pleasant side effects :-). Plus I totally dig the nasty talk! You say things you could never conjure with someone actually in front of you.
