Safe words and Safety
I advocate the use of safe words in sessions, as I feel its important for the sub to know that the session can stop at any time for whatever reason. This is not a reflection on the subs ability to play and not a criticism of the mistress if a safe word is used. BDSM play is a two way experience and for this reason the scene needs to be right for both parties to enjoy the session.
Hygiene
I believe that all equipment should be sterilised to hospital standards as dirty equipment literally puts people's lives in your hands. This is something that I take very seriously as there are a great many diseases that can be transferred should incorrect sterilising procedures be used. For metal instruments a medical autoclave is the perfect way to sterilise instruments, but when using non-medical attachments like those that accompany electro-stim, cold sterilising is the only way to clean to above hospital standards.
I also wear disposable latex gloves throughout each session and the room is throughly cleaned between appointments.
One of the main products I use is in the www.trisel.com range.
