I googled it....didnt get any responses showing anything about pain...but as far as the air itself everything says to make sure you're using enuff lube and that the positions can cause/help the problem....what I've read says rear entry is the worst one for that and you being on top seems to decrease the problem
I'm not posting any actual information links because just about everything it brought up for me was other message boards and I didnt want to get one someones bad side by linking another message board
