well thanks everyone for the compliments. The reason I was wondering is because I've had girls complain of being sore afterwards. Seeing as how I'm the type that once is never enough, I don't want her to be too sore to continue. I learned a long time ago to listen to my partners body language but since she only starts hurting once she comes down from the last of many orgasms by then it's already too late.

I'm looking more for a what NOT to do than what to do, I've got quite a few of my own little tricks and I'm just looking to remove the soreness factor.
