well sis, its allways hard adjusting at first to addressing your man appropriately, our society and the way we are raised to conduct ourselves is so informal these days
is it any wonder considering the majority of your life the only men we sir might have been our fathers and mabey a work related customer service experience, i allways had to call my owner Master which is a slightly harder honnorific title to get used to in my opinion due to its format etc, imajine the girls trying to get used to using Lord, (in addition to which some men dont want thier girls using such titles in mixed company so its again harder to make it a habital practice without negative and or positive reinforcement (lord knows i cried myself many timeswhen i screwed up with my conduct), but trust me eventually and it will be sonner than yu think, with exposure and famiularity you will be rolling the sirs of yur lips with alacrity and be quiet comfortable doing so, so much so yu may start slipping the sir in there in front of people and places yu normally wouldnt by acciedent
also it may be easier to keep your head when online as you are not in his presence directy? i know it is for me, i still get flustered sometimes myself in the oddest of ways
if he is a new dom rope bondage may be unfamiluar to him as well as many other things unless he was aboyscout extrodinare or in a military job or a cowboy knot tying just isnt somethimng most people learn about anymore, try just leaving the bonds be( unless he is having yu struggle or escape them on purpose) cuffs of many kinds can be fun too, it will be hard to approach him about the knots is what i am sure yu are thinking yu may be affraid to bring it up, bruise his ego etc, its just like us with some things too, talking and communication is key, i am sure he is self aware of any problems he is having with the knots especially is every time he turns around poof there yu are free, eaither keep getting out of them until he learns himself under his own power thru other means to tie better ones, or try getting him a book on knots and rope tieing, mabey suggest a web site on it that provides tutorials and pictures
a google or boolean serch may help, and some here may have some links to good web sites for it, as for a book, yur local barnes and noble or books a million or public library should sufice, yud be surprised
