Hmm so you want to bleed? I make a distinction between light bleeding and heavy bleeding. I usually treat the latter as a hard limit (though there was one session in 2015 where I waived that so maybe it is a soft limit) Sometimes when I try to explain this to someone I have never sessioned with before they get confused and think I am requesting light bleeding. No, the issue with me is I often tend to bleed easily and I want to make it clear that they do not immediately have to stop if there is a little trickle (some Dommes will stop)

As for marks I am perfectly OK with them as long as they completely disappear in 10 days. However marks per se are not a goal either. What is a goal is being sore for at least 48 hours after the session. That I consider an integral part of a serious CP session. Marks and soreness are correlated but not perfectly.

As for pain tolerance a few suggestions:

Do not have an orgasm within 72 hours of the session. Edging a few times the day before may help as well.

A good warm up is essential.

Pacing is also important. She should take her time and insert a few breaks. Maybe let you briefly do something sensual before starting again

Not everything at the same intensity I also notice you don't have paddles on your list of instruments. Mixing dull bruising pain with sharp stinging pain works for me.
