I'm an experienced submissive and I am truly proud to wear whip marks from my Mistress. Like most, however, I need much improvement in my tolerance level. A question for Mistresses and slaves/subs - what is the best way to increase tolerance level? Obviously, it is by doing and experiencing, but do you start with shorter whips and work you way up or just gradually increase the number of lashes and duration? I don't think I can ever handle bull whips, but what is the hierarchy within the whip spectrum? By the way, the longest duration of marks lasting on my butt and back is about 2 weeks.
