I am not sure what all you have tried as a previous poster said...but I currently belong to a long distance Master. Like you, he has opened my eyes to so many wonderful things and I could never thank him enough for that. But as to your question....how do you feel about anything in public? This wasn't something that used to be big on my list, until I was asked to do some things in public and wow I am such a huge fan now and it's one of my favorite fantasies. I do not know if you talk on the phone or just on the computer, but if you do talk on the phone...perhaps him talking you through ie. phone sex in a public bathroom....at work, etc. I do not know if this would be possible or if it something you have already done. Just an idea.....I hope it helps.
