Good Question
1. A regular is a man 'client' that an woman 'SP' sees on a regular basis. Whether it's once a week, every 2 weeks, once a month, etc.
2. I never have a guard up only my wits about me. The person I am in my RL is the same person I bring to my job and the people that have seen me or spoken to me know this.
A persons comfort level is different for everyone which means a persons comfort level time span varies. Some people may never reach the comfort level you wish/want them to have, but I feel that has more to do with 'clicking'.
If you don't 'click' with the person you'll never get their comfort level and vise-versa.
